Understanding the cost of mirror wills is essential for couples planning their future together. While the idea seems straightforward—two nearly identical wills reflecting shared wishes—the pricing can vary widely depending on how and where you create them.
Many people assume mirror wills are always cheap, but that’s not always true. The cost depends on complexity, legal support, and long-term needs. Whether you’re exploring a will writing service or comparing options like mirror wills services, knowing what you’re paying for makes all the difference.
Mirror wills are two separate legal documents, typically created by couples, that reflect nearly identical instructions. Usually, each partner leaves everything to the other, and after both pass away, assets go to children or chosen beneficiaries.
They are especially popular among married couples and long-term partners because they simplify estate planning and reduce costs compared to drafting two completely independent wills.

The price of mirror wills varies depending on the method you choose. Below is a realistic breakdown:
| Service Type | Typical Cost (UK) | Best For |
|---|---|---|
| Online will services | £90 – £200 | Simple estates |
| Will-writing companies | £150 – £400 | Moderate complexity |
| Solicitors | £300 – £800+ | Complex estates or legal advice |

Two couples could pay completely different amounts for mirror wills. The difference often comes down to:
Most people focus only on the upfront price. That’s a mistake. The real cost includes long-term factors that often go unnoticed.
A simple estate with one property and basic savings is cheap to structure. Add multiple properties, overseas assets, or business ownership, and costs increase quickly.
Basic wills may not include protections against remarriage risks, inheritance disputes, or tax inefficiencies. Adding these protections raises the cost but significantly improves outcomes.
Mirror wills are not legally binding between partners. One partner can change their will after the other dies. Some people pay extra for structures that reduce this risk.
Life changes—children, property, divorce—require updates. Some services charge for every change, while others include lifetime updates.
Choosing executors and planning probate support can influence pricing more than expected.
Many services advertise low prices but add costs later. Here are the most common hidden fees:
These can easily double the total cost over time.
Some couples consider writing two separate wills instead. The comparison looks like this:
| Type | Cost | Best Use |
|---|---|---|
| Mirror wills | Lower combined cost | Couples with shared goals |
| Single wills | Higher total cost | Different beneficiaries or complex needs |

Mirror wills in the UK typically cost between £200 and £600 for both partners when using professional services. Online platforms may offer lower pricing, sometimes as little as £90–£150, but these usually suit only simple estates. More complex situations involving multiple properties, tax planning, or trusts can push costs above £800. The key is not just the price but what’s included—some services offer updates and legal guidance, while others charge extra for every change. Always consider long-term value rather than the initial cost.
Yes, mirror wills are generally more cost-effective than creating two separate wills. Because both documents share similar structures and instructions, providers often bundle them at a reduced price. However, the savings depend on how similar the wills truly are. If each partner has significantly different wishes, the cost advantage disappears. Mirror wills work best when couples have aligned goals, such as leaving everything to each other and then to shared beneficiaries.
Online will-writing services can significantly reduce costs, especially for simple estates. However, they may lack personalized legal advice and safeguards against complex issues like inheritance disputes or remarriage risks. While online tools are convenient, they are best suited for straightforward situations. If your estate involves multiple assets or legal nuances, investing in professional guidance may prevent costly problems later.
Mirror wills are not legally binding agreements between partners. This means one partner can change their will at any time, even after the other has passed away. This flexibility can create risks, especially in cases involving children from previous relationships. Some couples address this by using trusts or mutual wills, which are more restrictive but offer greater security. Understanding this limitation is crucial before choosing mirror wills.
Yes, ongoing costs can arise depending on the service used. These may include fees for updates, document storage, and legal consultations. Some providers offer packages that include lifetime updates, while others charge per revision. Over time, these costs can exceed the initial fee. It’s important to ask about long-term expenses upfront to avoid surprises later.
Not always. A solicitor is recommended for complex estates, high-value assets, or situations involving tax planning and trusts. For simpler estates, online services or will-writing companies may be sufficient. The decision depends on your specific circumstances and how comfortable you are handling legal details. Many couples start with basic services and upgrade if their needs become more complex.
Mirror wills should be reviewed every 3–5 years or after major life events such as marriage, divorce, having children, or buying property. Regular updates ensure that your wishes remain accurate and legally valid. Failing to update your will can lead to unintended consequences, including disputes among beneficiaries. Some services offer free updates, which can be a cost-effective way to keep your documents current.
