In order for your ex to occupy the home until her death, you would need to create a Will. You can find forms to create a Will in any business retail chain such as Staples or Kinkos or other retailers which sell business forms. You could also order blank forms via the Internet.
When you create the Will make certain that your wishes are clear and detailed. To validate the Will you will need several witnesses and sign in front of a Notary Public. After completing and notarizing the Will make sure you provide copies to your ex and your daughter.
