It states that if the property is sold it should be divided as 40% of the property is to go to my sister in law. 20% to myself and 20% to be divided equally between my three children. My sister in law can reside in the property as long as she likes and up to her death. It is a trust will, so none of us can leave any of our share to anybody else, the % of the person who has died then gets divided between those left. If she chooses to reside in the property she is responsible for the upkeep inside and out and is stated in the will. She has spent all her money £45, 000 on renovating the property and she wanted me to sign something to take that off the amount received for the house should she sell it. In fact she wanted me to sign and agree to what the property was worth in 2010 even if she doesn't sell it for ten years. I haven't signed anything as it is a trust will. My worry is if she sells the house, a conveyor would never know there is a restriction on it. My sister in law says we are nothing more than beneficiary's and do not need to be on the deed's.
