A personal guarantee can connect another person's or business's obligations to your own financial position. Treat it as a separate decision from whether you support the borrower or believe the business will succeed. Obtain the complete documents and ask for independent advice about what is proposed, how the obligations may change and what would be needed to end the arrangement.

Collect the whole document set

Ask for the guarantee, the underlying loan or contract, any security documents and relevant conditions. Identify the borrower, lender, guarantors and the purpose of the arrangement. A signature page alone does not explain what you are being asked to promise.

Tell the adviser about any proposed signing date and whether someone is pressuring you to proceed. Ask what information is missing and whether further financial or valuation advice is needed. Do not assume the other party's adviser represents your interests.

Ask what can become your responsibility

Ask the adviser to explain the obligations covered, any stated limit and how interest, fees or changes may be treated. Identify any proposed security over your assets. The practical question is what events could lead to a demand against you and what you would need to understand at that point.

Keep the discussion tied to the actual wording. Guarantees differ, and a general explanation from a friend or lender is not an assessment of your document. Ask for a clear account of assumptions and issues that remain uncertain.

Consider changes and the way out

Ask what happens if the borrowing increases, the arrangement is renewed, the business changes hands or your relationship with the borrower changes. Find out whether notice, consent or another step is required under the proposed terms.

Discuss release conditions before signing. Selling an interest in a business or no longer benefiting from the loan should not be treated as automatic confirmation that the guarantee ends. Ask what written evidence of release would be needed and who must provide it.

Make the decision with the right information

Review the advice alongside your own capacity to bear the potential obligation. Ask a suitable financial adviser or accountant about financial questions outside the legal review. Supporting another person and accepting a legal commitment are different decisions.

If you proceed, retain the final signed documents and advice, not just a draft. Record how you will receive relevant information about the underlying arrangement and when you should revisit the advice. If a demand later arrives, obtain advice about that document promptly.

Common questions

Does leaving a business end my guarantee?

Do not assume it does. Ask about the actual agreement, release requirements and written confirmation needed from the relevant party.

Is the lender’s explanation enough?

An explanation of the lender’s process is not necessarily independent advice about your interests. Ask a suitable adviser to review the actual documents and explain the implications for you.
