What are joint wills?
A joint will is a single, united expression of a couple's wishes for dividing up their estate. Unlike separate, individual wills, a joint will is a single document that typically outlines how both partners want their assets to be managed and distributed after they pass away.
If you're married or in a civil partnership, a joint will can provide a clear and straightforward plan for your estate. It's a way to make sure your assets are passed on as you both would like, often with provisions that protect the surviving partner's interests while also outlining future inheritance for children or other beneficiaries.
Key reasons for choosing a joint will
Here's a breakdown of the main reasons couples opt to arrange a joint will.
Simple estate planning
Joint wills offer a streamlined way to manage your estate. By creating a single document, couples can keeps it simple, reduce legal paperwork, and make sure their wishes are fully aligned. This approach can save time and money, minimise conflicts, and provide clarity for family members.

These wills typically guarantee that the surviving partner receives the entire estate, which gives them immediate financial protection when the first partner passes away. The surviving spouse or civil partner can maintain their lifestyle without extra financial pressure during a difficult time.

Joint wills allow couples to make clear, binding arrangements for their children's future. You can specify exact inheritance terms, set up trusts, and ensure that your children's financial needs are met, even after both parents have passed away.

By creating a clear, mutually agreed document, joint wills can reduce the likelihood of disagreements within the family. Because these wills are explicit in their joint nature, they leave less room for interpretation, which can prevent costly legal disputes among beneficiaries.

If you and your partner are of one mind about your finances, a joint will could be the simplest approach to estate planning:
Individual wills
Individual wills offer more flexible and personal control. They allow each partner to make independent decisions about their assets, which can be helpful for couples with more complex finances or separate preferences about how their assets are divided up.
Joint wills
Joint wills offer a unified approach to estate planning, providing a single, detailed plan that reflects both partners' wishes. They're a clear strategy that can be especially useful for couples with simple estate distribution needs and shared financial goals.
Joint wills pros and cons
Advantages
- Unified vision: Comprehensive estate planning that matches your shared wishes and financial goals.
- Financial protection: Financial clarity for the surviving partner, reducing uncertainty and disputes.
- Simplicity: Bringing two wills together as one document reduces legal complexity.
- Cost-effective: By avoiding two separate wills, you can save significant money on legal prep.
Disadvantages
- Inflexibility: Can be extremely difficult to cancel or modify, especially after one partner's death.
- Limited options: Challenging to update the will to reflect changes to one partner's life or finances.
- Reduced control: Tight restrictions can limit the surviving partner's autonomy and decision-making.
- Complex separation: If a relationship ends, joint wills become legally complicated to unravel.

Should I consider a joint will?
Couples with aligned views on inheritance, standard family structures, and the same financial goals often find a joint will to be highly practical. They simplify the complex world of estate planning with a clear, connected plan that speaks for both of you. But proceed with caution if your finances are more complex. A joint will can be restrictive for those with blended families or major assets. Talk to a specialist to help you find an approach that truly protects your family's finances.
Types of joint wills
1. Mirror wills
Although mirror wills are a joint strategy, each partner signs their own copy, so they're technically two separate legal documents. This means that each partner could revoke or change their own version during their lifetime, unless they've entered into a binding mutual will agreement.
These wills are largely identical, with each partner typically leaving their assets to the other. They're generally used by couples with similar wishes for their finances.
Because they're relatively flexible, they can be suitable if you're thinking of taking out a will with a business partner. If one person dies, the surviving partner may find them adaptable to the new financial situation.
Mirror wills are similar to reciprocal wills and the terms are often used interchangeably.
2. Mutual wills
More binding than mirror wills, mutual wills create a legally enforceable agreement between partners. Once one spouse or partner passes away, the surviving partner can't change the will's basic provisions, which means the original wishes of both partners are kept intact.
3. Conditional joint wills
These wills include specific conditions or triggers for asset distribution. These might include plans for when your children reach certain ages, graduate, or get married, or terms that prevent the surviving partner from inheriting if they remarry. They might also include complex trust arrangements.
These conditions and triggers allow for a detailed, flexible will that goes beyond simple asset distribution, giving families a more specific inheritance plan.
4. Testamentary trust joint wills
This type of joint will includes a trust mechanism, which allow for extra protection for beneficiaries and potentially tax advantages. This gives partners more sophisticated asset management and a more controlled inheritance process.

Frequently Asked Questions
Can we change a joint will after one partner dies?
Changing a joint will after one partner's death is typically quite difficult, especially with mutual wills.
Once a partner dies, the surviving partner is largely bound by the original agreement. This is so that the original intentions of both partners are respected.
That said, some flexibility might exist in exceptional situations. If your finances or personal circumstances change significantly, you might be able to make adjustments to asset management or address the new needs of your family.
The key is to consult a specialist solicitor who can provide guidance specific to your life and finances. They can help you understand the limits and options for changing the will while respecting its essential provisions.
How much does creating a joint will cost?
The cost of creating a joint will in the UK varies depending on several factors. Typically, you can expect to pay a few hundred pounds.
The price will be influenced by your estate's complexity and your solicitor's expertise. High street solicitors might charge at the lower end of the spectrum for basic wills, while specialist estate planning lawyers could charge more for complex arrangements.
Online will-writing services offer cheaper alternatives, but they may not capture all the nuances of your specific situation. For many couples, a professional solicitor brings peace of mind, ensuring their will is legally robust, comprehensive, and tailored to their family and financial circumstances.
Are joint wills suitable for unmarried couples?
Joint wills can be crucial for unmarried couples, who could face unique legal challenges when it comes to inheritance. Unlike married couples, unmarried partners don't automatically inherit assets if one partner dies.
This makes a professionally-written joint will essential for protecting each other's financial interests. Without a will, "intestacy" laws may leave the surviving partner with limited rights, perhaps forcing them to make difficult legal claims to access shared assets.
A well-drafted joint will provides clear instructions about what to do with your assets, ensuring that your partner is fully protected. It can also help manage any tax implications and address specific wishes about property, savings, and other assets.
The key is to work with an advisor who understands the finer legal points for unmarried couples.
What happens if we separate after creating a joint will?
Separation changes your estate planning needs, and most joint wills become invalid or require full revision when a relationship ends.
You'll need to take prompt action to protect your individual interests and update your estate planning. This typically involves completely rewriting your existing will to match your new situation. Your shared finances, property ownership, and ongoing obligations may all need thinking through.
Many solicitors recommend creating entirely new individual wills that clearly separate your assets and intentions. It's important to address this quickly to make sure your assets are protected and distributed according to your wishes. Any delay can leave you vulnerable to unwanted outcomes for your inheritance.
Can joint wills provide for children from previous relationships?
Joint wills can be useful for managing complex family structures, especially when there are children from previous relationships. You can create detailed provisions that ensure inheritance is fair to all children, regardless of their relationship to both partners.
This might include setting up trusts, defining exact inheritance percentages, or creating staged inheritance plans. You could specify that children from previous relationships receive certain assets or a fixed portion of the estate, for example, while making sure your current partner is also financially protected.
Your solicitor or professional advisor can draft precise, legally binding clauses that reflect your family's dynamics and your wishes for your children.
How quickly can a joint will be processed after death?
The probate process for a joint will typically takes between six to twelve months in the UK, though the timeline can be extended if things are more complex. Your estate's size, potential disputes among beneficiaries, and your executor's approach can all slow the process down.
Other complications include property sales, business asset management, or challenges to the will, all of which can stretch out the timeline. Executors may need to value the estate, pay any inheritance tax, or obtain a grant of probate, before they distribute the listed assets.
A clear and well-prepared joint will can streamline this process. Keeping detailed, up-to-date financial records and choosing an experienced executor also help ensure a faster, smoother process.
