We know separation changes more than daily life. It can alter legal rights, financial outcomes and who looks after your interests if you lose capacity.
After a Final Order, the old spouse exemption ends. Large gifts or settlement transfers can become potentially exempt transfers and may trigger unexpected tax bills if timing is poor.
We’ll set out practical steps to protect your children and keep control of what you leave. We explain, in plain language, what sensible estate choices look like for British homeowners.
We also flag common risks: outdated wills, informal gifts and transfers made at the wrong moment. With the right structure and advice, you can reduce risk and ring‑fence value without creating new problems.
Key Takeaways
- Divorce changes legal exemptions and can affect what your family receives.
- Poor timing on transfers can increase liability by tens of thousands of pounds.
- Review wills and transfer arrangements soon after separation.
- Clear documents protect children and preserve control over assets.
- Professional advice helps reduce risk and avoid costly mistakes.
Why estate planning changes when you’re getting divorced or newly separated
A split at home quickly turns everyday money decisions into long-term estate questions.
Priorities shift. You may still trust your co‑parent, but you may no longer want them to control assets meant to benefit your children. That changes who should receive what and when.
There is often a life‑admin gap. People delay updating wills and records while still making big financial moves. Those informal actions can have costly consequences.
How changing family dynamics can affect your child’s share
New partners, blended households and adult children moving back change what feels fair. You might want to ring‑fence property or cash so it protects your bloodline rather than new household claims.
The hidden tax cost of “informal” financial support and gifts
Gifts or paying an ex’s mortgage might feel helpful. But the system looks at legal form and timing, not intent. That can create unexpected tax exposure on the estate.
“We once saw a lump sum paid to a former partner that later increased the estate charge by tens of thousands.”
- Review big transfers before you act.
- Seek expert advice when supporting a lower‑earning spouse outside an order.
- Use formal orders or trust steps to protect what you want to leave your family.
Separation vs divorce finalised: the legal and tax milestones that matter
A permanent split brings clear legal dates that matter to asset protection and future charges.
What changes at permanent separation
Once separation is permanent, some reliefs change. Capital gains “no gain, no loss” for transfers between former spouses runs only for three years from the end of that tax year.
What changes when the Final Order is made
When the Final Order is sealed the spouse exemption for IHT ends immediately. After the divorce finalised, gifts that were safe may become potentially exempt transfers with a seven‑year risk.
Why “bad timing” can increase inheritance tax by up to £130,000
Lose the spouse exemption and a £325,000 transfer can face a 40% charge — about £130,000. That simple example shows why coordination matters more than rushing.
- Check key moments: moving out, agreeing terms, issuing proceedings and approaching the Final Order.
- Align legal steps and financial moves in time to reduce exposure.
We’re not suggesting you game the rules. We recommend sensible timing to avoid accidental IHT and keep more for your children.
inheritance tax planning for divorced parents uk: the core IHT rules you must know
The day a decree is sealed, some family protections stop and fresh rules start. We set out the essentials you need to protect a child’s share without drowning in legal detail.
How the spouse exemption works and when it ends
While you remain legally married or formally separated, most transfers between spouses are safe from inheritance tax. That safety ends the moment the Final Order is made.
Practical point: transfers that seemed harmless during separation may become chargeable once divorce is final.
Potentially exempt transfers and the seven‑year rule
A gift made after divorce can be a potentially exempt transfer (PET). If the donor dies within seven years, the gift may count against the nil‑rate band and generate an IHT bill.
- Death within three years: full charge may apply.
- Between three and seven years: taper relief can reduce the charge.
When maintenance payments escape IHT
Regular maintenance to a former spouse and to a relevant child of the family is usually exempt from IHT. Correct labelling and clear records make that outcome far more reliable.
Why one‑off gifts to children can be risky
Gifts for a deposit, car or renovations are often seen as ordinary gifts, not maintenance. If death follows within seven years, those transfers can reduce what reaches other heirs.
“We always check whether a payment is maintenance or a gift before we recommend action.”
Where estates are large or cross‑border, we usually advise bespoke advice. Small changes in wording or timing can save tens of thousands in IHT.
Structuring divorce settlements to reduce IHT risk
How you frame a settlement often matters more than the headline figures. We focus on the paperwork and dates that shape whether a transfer is exempt.
How court orders can create IHT-efficient transfers after the Final Order
HMRC accepts transfers made after the Final Order that follow a court order from divorce proceedings as exempt, provided there is no intention to give a gratuitous benefit.
Practical point: an agreed order sealed by a court can make a lump sum or asset transfer part of a legitimate financial settlement rather than a gift.
Property adjustment orders and why the effective date matters
Property adjustment orders only take effect from the Final Order. That timing affects when ownership changes and which rules apply.
Moving too early can create exposure. Waiting for the effective date can preserve the exempt treatment.
Using agreed orders to plan without “gratuitous benefit” issues
“Gratuitous benefit” means a transfer intended as a gift. Most payments to balance a settlement are not gifts.
“We treat clear, documented transfers under a court order as part of the settlement, not as gratuitous gifts.”
- Keep the sealed order, transfer dates and bank records.
- Record the purpose (eg to rehouse the other parent or equalise assets).
- Work with family and private wealth advisers so the legal steps and finance match.
| Order type | When effective | Usual effect on transfers |
|---|---|---|
| Agreed financial order | When sealed by the court | Allows exempt transfers if not gratuitous |
| Property adjustment order | From the Final Order date | Changes title; timing vital to treatment |
| Informal agreement | Immediate (no court seal) | Higher risk of being treated as a gift |
Trust planning after divorce to secure wealth for children
A well-drafted trust turns short-term family upheaval into long-term financial security for children.
We explain when a trust is the seatbelt in a post-split estate plan. It is about control and protection, not complexity.
Creating a children’s trust within proceedings
Key benefit: if a court orders the trust as part of a settlement, the usual immediate 20% lifetime charge need not apply.
This route lets clients fund a trust that supports children now while preserving long-term wealth. It can also pay a partner during their lifetime without destroying the children’s ultimate share.
Trustees and staged access
Choose a mix of family and professional trustees to balance knowledge and neutrality.
Access can be staged as children age. That prevents a full payout at 18 and protects against poor choices.
| Feature | Typical effect | Practical note |
|---|---|---|
| Court-ordered children’s trust | Avoids immediate 20% lifetime charge | Needs clear wording in the order |
| Support for partner | Allows lifetime payments without harming children’s share | Set strict conditions and limited powers |
| Trust governance | Letters of wishes and decision rules | Reduce disputes; ease trustee decisions |
Administration matters. Proper records, regular trustee reviews and clear letters of wishes keep the trust aligned with wider estate goals.

The family home, property and children living at home: planning without backfiring
Giving a share in your property can work — but only if behaviour, paperwork and timing match.
We cover common situations where adult children live at home and parents want to protect value without creating trouble. A gift of a share is usually a potentially exempt transfer. If the parents survive seven years, that share can fall outside their estate.
Gifting a share of the home
A gift to a child who lives in the house is a PET. Survive seven years and the value normally sits outside your estate.
Gifts with reservation of benefit and shared occupation
If you give away value but still live as before, HMRC may treat it as retained. Shared occupation often reduces that risk where the child genuinely benefits from their share.
What if the child later moves out?
The position should be reviewed if the child leaves. That change can affect whether the original gift still achieves its purpose.
Downside risks and fairness
Risks include the child’s divorce, bankruptcy or disputes that force a sale. These events can erode the intended protection.
| Issue | Typical effect | Practical step |
|---|---|---|
| Gifting a share | PET; seven-year test | Document date and intent |
| Shared occupation | Lower GROB risk | Keep evidence of genuine benefit |
| Child moves out | Review position | Consider trust or deed of variation |
| Siblings’ fairness | Resentment or dispute | Use cash balancing or clear agreements |
We recommend clear paperwork, open conversations and early reviews. That keeps the family home working as a safe legacy rather than a future source of conflict.
Capital Gains Tax and divorce: protecting value in the former matrimonial home
Protecting value in the family house starts with clear agreement on whether separation is temporary. Small choices around ownership can create large, lasting costs if not handled with care.
Principal Residence Relief during trial separation
If a couple agree the split is a trial separation, the absent spouse can usually retain entitlement to Principal Residence Relief. That keeps a move out from triggering an immediate capital gains charge on the family property.
“No gain, no loss” transfers and the three-year window after separation
When separation becomes permanent, transfers between spouses benefit from “no gain, no loss” treatment for three years from the end of that tax year. After that time, a disposal can create a chargeable gain on the asset transferred.
Why formal divorce settlements can remove the time limit
A transfer made under a formal settlement or court order usually keeps the spousal exemption indefinitely. That removes the three‑year clock and protects the value of the home and other assets when ownership changes.
- CGT is often the silent issue when property and other assets move in a hurry.
- Timing, clear records and an agreed status can preserve value.
- We recommend early coordination with advisers; see our capital gains guide for more detail.
Income tax after divorce: shares, bonds, maintenance and who is taxed
When investments move between former partners, so does the bill on the income they produce. Transfers under a formal settlement do not trigger income tax at the point of transfer. The key point is who legally owns the asset after the move.
Income-producing assets and marginal rate exposure
If you transfer shares or a portfolio of bonds, the new owner pays any dividends and interest. That person is taxed at their own marginal rate from the date of transfer.
Practical point: giving an investment to a lower-earning parent can cut the annual charge. But it can also shift future growth and rights to returns.
Why maintenance usually sits outside UK tax
Regular maintenance payments are normally not taxable for the recipient. They also do not give the payer any income relief.
- The tax on income follows the legal owner, not the intent of the settlement.
- Record the exact transfer date and paperwork to avoid disputes about who declared the income.
- Seek specialist advice when overseas income, complex trusts or business assets are involved.
“Tax is rarely the only driver, but it often decides whether a plan supports children long term.”
Wills after divorce: preventing an ex-spouse inheriting and avoiding intestacy
Your Will does not automatically change when you separate; that truth surprises many. A separation can leave your documents out of step with your wishes. We recommend a quick review as soon as practical.
Why separation alone does not change your Will or intestacy outcomes
While you may live apart, the law treats your Will as unchanged. A separated spouse can still inherit under a Will or by intestacy unless you act.
What changes at the Final Order
When the final order is made, the former spouse is generally treated as having died for gifts and appointments.
An ex named as executor or trustee is usually revoked automatically. That can leave your estate with gaps.
Updating gifts, liabilities and foreign assets
Failing to update beneficiaries or to note foreign assets can create partial intestacy or unintended burdens on children. Make clear notes about ongoing obligations to a former spouse.
| Issue | Effect on estate | Practical step |
|---|---|---|
| Separated but no Will change | Spouse may still inherit | Review and amend Will |
| Final order made | Gifts to ex fail; executor removed | Name replacements; record dates |
| Foreign property | Different rules overseas | Get cross-border legal advice |
| Ongoing obligations | May affect net estate | Document payments and purpose |
“Update your Will early so the people you trust stay in place.”
Starter checklist before you see a solicitor:
- List beneficiaries and guardians.
- Note executors and replacements.
- Record any foreign assets and ongoing payments.
- Bring copies of any court orders and financial records.
These steps help protect your children and keep assets in the hands you trust. If you need specific legal advice, speak to a solicitor experienced in estate planning and post‑final order issues.
Lasting Powers of Attorney after divorce: who can act for you if you lose capacity
Who holds the keys to your finances and care if you lose capacity matters hugely after a relationship ends.
LPAs let named people make decisions about money or welfare when you cannot. They are central to post‑split planning.
When an ex-spouse’s appointment ends automatically
Divorce usually cancels an ex‑spouse’s role as attorney unless the LPA explicitly says they may continue. That exception is rare but important.
Joint and several attorneys, replacements, and common validity traps
The practical difference matters. Joint attorneys must act together. Several attorneys can act alone. That affects how quickly banks pay bills or carers make choices.
- Joint appointments can fail if one attorney loses authority.
- No replacements named leaves documents unusable.
- Restrictions or unclear wording create disputes at a critical moment.
“We tell clients to review LPAs early so questions are fixed while capacity is intact.”
Simple review: check who is appointed, name replacements, note any restrictions and get prompt legal advice.
We offer a clear service to help individuals and clients update LPAs and protect children and other loved ones from inappropriate control by an ex or current partner.
Non-domiciled and cross-border issues: remittance basis pitfalls in divorce settlements
Cross-border splits bring an extra layer of rules that can quietly turn offshore savings into a UK charge. We explain the practical risks and the simple steps that reduce exposure.
What is the remittance issue? If you use foreign income or gains in the UK it can be treated as a remittance. That includes bank transfers, buying UK property, or paying a UK service with offshore money.
Relevant person rules matter while you remain married. If your spouse brings offshore funds into the UK, HMRC can treat that as your remittance. That risk usually ends once the divorce finalised date is reached.
Sehgal and Meehan — recent clarity
After Sehgal and Meehan, HMRC accepts there is no taxable remittance where settlement funds stay offshore until the Final Order and no relevant person benefits in the UK. That gives a clear way to protect value if you follow strict records and ring‑fence accounts.
- Document sources and dates.
- Keep settlement money offshore until proceedings conclude.
- Avoid using foreign funds to pay UK bills while still married.
The abolition of non-dom status from 6 April 2025 changes the landscape, but remittance rules still apply to pre‑6 April 2025 income and gains. Get specialist advice early when overseas money or assets are involved — mistakes are hard to unwind and a good adviser can save time and cost.
See our non-domicile guidance if your settlement touches offshore funds or cross-border assets.
Conclusion
A clear set of dates and documents is the simplest way to protect what matters most.
Separation alone does not change Wills or intestacy. The Final Order does change spouse protections and can turn casual gifts into potentially exempt transfers (PETs). Court‑sealed orders and carefully drafted trusts give safer routes to preserve value for your children.
Watch property moves closely. Gifts of a share in the family home can be effective, but retained benefit rules and a child leaving later can undo that aim. CGT and income changes also affect the long‑term fairness of any settlement.
Practical next step: list your assets, note key dates and get coordinated legal and tax advice. If you want an accessible starting place, see our guide to protect your family’s future.
