Here is why you don't do something for simplicity's sake:
My grandmother bought a second home at the Jersey Shore in the 1950s. Tiny place in Brick - if you know the area, you know that we are not talking Spring Lake or Mantoloking. She (widow) would use it in the summer with her sons (my dad and his brother.) As she got older, she lost interest and my dad and my uncle each bought their own beach houses, so she would visit there and let her cousins, nieces, nephews, etc. use it. About 10 years ago, one of her nieces was using it a lot (and to her credit, keeping it up, gardening, etc.) and asked to be added to the deed, supposedly because the cable company wouldn't let her order cable/internet for the house without her name being on the lease. RED FLAG. My lovely trusting grandmother added her to the deed, without telling her sons until much later.
Well, you can guess what happened: she moved in, moved her family in, moved her daughter's boyfriend in ... and won't leave. My grandmother died five years ago leaving the house (her share of it) to my dad and his brother. They want to sell it but the niece can't afford to buy them out. So basically everything is stuck and is a disaster. I don't know how they're going to settle it but it is causing so much bad blood on all sides.
DON'T DO THINGS FOR SIMPLICITY'S SAKE, EVEN WHEN IT'S FAMILY!!!
