You will also need to submit a signed statutory declaration, which should include your names and be signed by you and your partner (if applicable) in the presence of a solicitor, and the solicitor's name and address must also be included. A copy of such form is attached.
The solicitor/commissioner of oaths may charge for this service, and therefore it might be better for you to wait until you have gathered all the necessary information before securing the statutory declaration. The lawyer/commissioner of oaths must put a stamp bearing his name and address on the statement.
You must comply with this rule while you own the affordable house, and you will have to confirm the fact at the end of each year.
