For many of us marrying more than once is not unusual. Often this is because your first spouse has died and in these circumstances you might want to be sure that you provide for your current spouse but also for your family. This can be achieved with a life interest trust which allows the second spouse, for example, to live in your house until they die and thereafter for the house to be sold and the proceeds divided amongst your children. A more common husband and wife will may not be appropriate as your children may not inherit from your second spouse if he or she left everything to his or her own children. Similarly it would not be fair to leave everything to your children in your will as your second spouse would have to leave their home and face the possibility of having nowhere to live. Life interest trusts are flexible so you can provide that the right to live in a house (or enjoy income from capital) terminates should your second spouse remarry.
