<prompt> Human: Hello rpersonalfinance, my sister and my brothers wife are both expecting their first children this summer. I want to gift the children each 1000 in the form of a trust and expect to continue to contribute to it during their lifetime. I want to place their parents ultimately in charge of the trust but I dont want to give them complete control of the money because my brother especially is notoriously bad at saving money. How should I do this and do I have to wait until the children are born? Do my brother and sister need to be aware of the gift before the trust is created or can I create it and assign it to them? Any help would be appreciated. Thanks!  <response>: In the eyes of trust law an unborn child doesnt exist, so you cant close the class until they are born. However, you can make a trust with conditions that would close the class. For example, the first natural descendant of your brother born in the year 2018. Once your brother has a natural descendant in 2018, the class can be determined and is closed. Then you can amend to name the child specifically as beneficiary. You dont need to inform the parents. But any disbursements from the trust are going to fall under their control. You can set the trust to disburse after the children reach the age of majority, though.
