We just went through this with a trust with my Dad's DVC contracts. He set up a revocable living trust through his attorney to put his real estate assets into, including his DVC contracts. My brother and I were added as co-trustees on the trust. We did some some research here, and other places as well, and found it to be safer than just adding us to the deeds, but allowed us to become co-members on his contracts. The process (after setting up the initial trust) was pretty easy, we worked with the Title company Disney recommended. ROFR was signed off almost immediately after it was filed and we're just waiting for the final papers from Disney. My dad did it for a few reasons, not only the membership, to to avoid probate at some point in the, hopefully long time away, future. It's also a safer way to set things up in the event an adult married child has some difficulties (financial or marital) in the future as the trust is it's own entity.
