If you are asked to guarantee someone else's borrowing, such as a relative's loan or a business you are connected to, the lender will usually require independent legal advice before you sign. A solicitor explains your liability and signs the ILA certificate the lender needs.

A personal guarantee is a promise to pay another person’s or a company’s debt if they don’t. The lender can then claim the money from you personally, which can put your savings and, in some cases, your home at risk.
Guarantees can be limited to a fixed amount or unlimited, and may cover future borrowing as well as the current loan.
Following Royal Bank of Scotland v Etridge (No 2) [2001], lenders take steps to make sure a guarantor understands what they are signing and is not under pressure or undue influence, particularly where the guarantor receives no direct benefit. The usual step is to require advice from an independent solicitor, who confirms this in a certificate.

Speak to your solicitor
An SRA-regulated solicitor explains the risks in plain English, by video or in person in London.
Certificate sent to your lender
Your signed ILA certificate and documents are dispatched, usually the same day.
Yes. Most lenders accept advice given by video call, so you can usually be advised from home. If your lender insists on a face-to-face meeting, that can be arranged in London instead.
You don't need one nearby. Our SRA-regulated solicitors advise by video call wherever you are in England and Wales, often the same day, and video advice is accepted in most cases. If you need to meet face to face, appointments are available at the solicitor's office in London.
Family guarantees are exactly where lenders want independent advice, because of the risk of pressure. Your solicitor will speak to you on your own to make sure the decision is yours.
It depends on the wording. Some guarantees can be ended for future borrowing, but you usually stay liable for what is already owed. Your solicitor will explain the terms.
Often the same day. Once your solicitor has your documents and has advised you, the signed certificate is usually sent to your lender, broker or conveyancer the same day.
Independent legal advice starts from {price} per person. Your solicitor confirms the fixed fee on your free consultation, before any work starts.
