Write Your Own Loan Agreement
Yes, you can do it without a lawyer.
You don't necessarily need a lawyer to write your loan agreement. You can find examples of loan agreements in many business books; just write up the same information, complete it and sign it. If you decide to get legal advice, you can save money by drawing up the loan agreement yourself and then giving it to an attorney to redraft.
