if you purchase any property( house, car...etc ) and having a proper title on it is very important.
For example, to buy a house. Husband and wife wanted to own a house. The situtation is only 1 party is working, the other is staying at home. They want to BOTH own the house, meaning their names are on title.
If you are buying the house you live in ( not rented out ), there will be no issue until u sold the house. If you buying the house and will be rented out, having both name on title can have a better arrangment on tax issues.
There are lots of possible situtation. If you have more question, feel free to QQH me or reply to this posting. Try my best to answer you.
