My grandmother made a will to put the house in my name.after her death my dad who was on the original deed switched the deed to his name and my moms name along with my uncle and his wife.what stands?

If your grandmother was the SOLE owner of the property when she died then she was able to devise the property to you in her will. If that is the case then her will would need to be probated in order for the title to the property to pass to you and your father's deed to himself and others would be null and void. However, you said that your father was on the original deed. If your father's name was on the deed to the property as the sole owner then he owned the property and your grandmother couldn't devise it to you in her will. In that case the gift to you in the will would be null and void. You can verify who was the last legal owner by deed by checking the records at your local land records office. You need to check your father's name in the "grantee" index to determine if there is a deed to him dated before your grandmother's death. You may find that your grandmother conveyed her property to your father by signing a deed. For any further questions or to add details please use the discussion page.
