The purpose of the agreement is to record the terms of the loan between the borrower and the lender. As a lender you will want to lend money for the best return available and minimum risk. As a borrower your objective is to obtain funds with a degree of flexibility and the lowest possible cost. This agreement can be tailored either way and will provide you with a contractual framework for you to evidence the loan and set out the terms upon which the loan is made. Agreements are easier to enforce so you are best placed putting it in writing so it is clear from the start it is a loan and not a gift!
