The best tools built in; that’s a fact
By adding will search and will registration into your workflows, your teams can create flawlessly simple and effective processes that speed up and efficiently manage complex wills and probate cases.

Benefits of will search
Using will search as a standard step in every estate gives your firm an extra layer of protection with very little extra effort. It helps uncover unknown, outdated or superseding wills before distribution, reducing the risk of disputes, complaints and costly corrections later.
Making will search routine also demonstrates clear due diligence to clients, regulators and insurers, showing that your team actively checks for the full picture before progressing probate.

Benefits of will registration
Will registration turns each will you draft into a future‑proof asset for your clients and their families. By registering, you create a secure record of where the original will is held, making it far easier to locate when it is needed – even years later, or if clients move firm.
That visibility reduces the chance of lost, overlooked or competing wills, and positions your firm as one that takes long‑term client protection seriously rather than treating the will as a one‑off document.

Integration within OneAdvanced Legal
Because will search and will registration are integrated into OneAdvanced Legal, your team can access them from the same screens they already use every day. There is no need for extra logins, manual re‑keying or switching between systems; matter details and search activity stay linked in a single audit trail.
That makes it much easier to embed best practice – every fee earner can run searches and register wills as part of their normal workflow, rather than as an extra task they have to remember.

"Failure to search when applying for probate is a serious negligence risk"
Every day, law firms face the risk of a will being discovered after probate has been granted - and it’s the lawyer’s reputation that takes the hit. A single missed document can undo months of work, damage client trust, and even expose your firm to liability. The cost of inaction isn’t just financial; it’s professional.
As a OneAdvanced user, you already have seamless access to The National Will Register - the UK’s trusted record of more than 10.5 million wills.
Running a search takes minutes, but the peace of mind lasts indefinitely. Protect your clients, safeguard your firm, and make “we didn’t check” a phrase you never have to explain.
