A shared home, children, savings and plans for the future can make life feel settled. But estate planning for couples is about deciding what happens if one of you dies first, loses capacity or leaves behind wishes that have never been written down. A will gives you both a chance to make those decisions calmly, rather than leaving your family to deal with uncertainty at an already difficult time.
For many couples, the starting point is simple: each person needs their own legally valid will. From there, the right arrangements depend on whether you are married, in a civil partnership or living together, how you own your home, and who relies on you.
Estate planning for couples starts with the right questions
A will is not just a document about money. It is a set of instructions for the people left behind. It can name the people who should manage your estate, say who should receive your belongings and savings, and set out practical wishes that may otherwise be unclear.
Before making a will, talk through the decisions that affect you both. Who should inherit first if one of you dies? Should everything pass to the survivor, or should part of the estate be protected for children from a previous relationship? Who would look after your children if neither parent were alive? And who would be sensible, organised executors?
It can feel uncomfortable to discuss these subjects, particularly when you are busy raising a family or paying a mortgage. Yet putting off the conversation does not make the risks disappear. It simply means the law may make decisions that do not reflect your wishes.
Marriage, civil partnership and living together are not the same
Married couples and civil partners have certain inheritance rights if one partner dies without a will. However, intestacy rules do not necessarily produce the outcome a family expects, especially where there are children, substantial assets or previous relationships involved.
For unmarried couples, the position is more serious. Cohabiting partners do not automatically inherit under the intestacy rules in England and Wales, no matter how long they have lived together. A surviving partner could face a deeply upsetting situation: they may be left with no automatic right to savings, personal possessions or a share of a property owned solely by the person who died.
A will is the clearest way to provide for a cohabiting partner. It can also prevent avoidable disputes between a surviving partner and other family members who may inherit under the rules of intestacy.
Marriage or entering a civil partnership usually revokes an existing will, unless the will was made specifically in contemplation of that marriage or civil partnership. This catches many people out. If you have recently married, do not assume your earlier will still works as intended. Divorce or dissolution can also affect a will, so it is wise to review it rather than relying on assumptions.
Check how your home is owned
Your property is often the largest part of your estate, and the wording on the ownership matters. Couples commonly own a home as either joint tenants or tenants in common.
If you own as joint tenants, the deceased person’s share normally passes automatically to the survivor. This happens outside the will through the right of survivorship. It can be suitable where both partners want the survivor to own the home outright.
If you own as tenants in common, each person owns a defined share, which can be left by will. That can be useful for unmarried couples, for people with children from an earlier relationship, or where you want a surviving partner to remain secure in the home while ultimately preserving your share for your children.
A will cannot override the automatic survivorship rules that apply to a joint tenancy. Equally, changing the way a property is owned does not replace the need for a will. Your title deeds, mortgage arrangements and any declaration of trust should all be considered together, particularly if you contributed different amounts towards the purchase.
Mirror wills can make shared wishes easier
Many couples make mirror wills. These are two separate wills with similar or matching instructions. A typical arrangement leaves everything to the surviving partner, then to named children or other beneficiaries after the second death.
Mirror wills can be a straightforward, affordable option when a couple’s wishes are aligned. They allow each person to appoint executors, name guardians and decide who should benefit, while keeping the overall plan consistent.
There is an important trade-off. Mirror wills are separate documents, so the surviving person can usually change their own will later. That flexibility can be helpful after changing circumstances, but it may concern someone who wants to ensure that children from an earlier relationship eventually receive an inheritance. In that situation, a trust in a will or more tailored legal advice may be appropriate.
Do not confuse mirror wills with mutual wills. Mutual wills can involve a binding agreement not to change arrangements after one person dies, but they are legally complex and are not usually the right answer for ordinary family planning.
Choose executors and guardians with care
An executor deals with your estate after death. They collect assets, pay debts and bills, deal with paperwork and distribute the estate according to the will. Many couples appoint each other first, then name one or two replacement executors in case both partners have died or the survivor cannot act.
Choose people who are trustworthy and likely to cope with the responsibility. An executor does not need to be a financial expert, but they should be willing to communicate with banks, organisations and beneficiaries. It is sensible to ask them before naming them.
If you have children under 18, a will is also the place to appoint guardians. This is one of the most protective steps parents can take. The guardian would be responsible for your children’s day-to-day care if both parents died. Consider their relationship with your children, their own family circumstances, location and values, then name replacement guardians if possible.
A guardian appointment does not decide every issue automatically, as the children’s welfare remains paramount. Still, it gives those caring for your children clear evidence of your wishes.
Think beyond an outright gift
Leaving everything outright to a partner is often right, but not always. If one person dies and the survivor later remarries, becomes vulnerable to financial pressure or needs care, assets intended for children may not end up where the first partner expected.
A life interest trust in a will can sometimes offer a middle ground. It may allow a surviving partner to live in the family home or receive income from assets during their lifetime, while preserving the underlying capital for children later. This can be valuable in blended families, but trusts bring extra responsibilities and should be chosen for a clear reason rather than added automatically.
Estate planning may also involve pensions, life insurance and jointly held accounts. Some of these pass outside a will through nominations or survivorship, so check that your provider records are up to date. A will remains central, but it should not be the only document you review.
Make the will valid and keep it current
For a will in England and Wales to be valid, it must be made by someone aged 18 or over who understands what they are doing, is in writing, signed, and witnessed correctly by two people. Witnesses should be independent adults. A beneficiary, or the husband, wife or civil partner of a beneficiary, should not witness the will because their gift may fail.
Once signed, keep the original somewhere safe and tell your executors where it is. A perfectly drafted will is of little use if nobody can find it. Will storage can provide reassurance, particularly if important papers are easily misplaced at home.
Review your arrangements after major life changes: moving home, marriage, separation, the birth of a child, a death in the family, receiving an inheritance or a significant change in finances. You do not need to rewrite a will every year, but a regular review can reveal whether it still protects the people you intended.
Making wills together is not about predicting the worst. It is a practical way of looking after one another, protecting your children and making sure the people you love are not left to guess what you would have wanted.
