Naming it to other people is a smart strategy to steal from her husband! Even she is married to her husband if she buys properties and put it into siblings, children or parents name this does not give her husband rights to claim it back! The same way as what my mother did!
Here's a sample story for you;
I bought properties and I trusted my mother so it was put under her name and when I come home from abroad, the properties is already sold. I tried to do something about it, but the fact that it was under her name temporarily while I was working abroad, this gives her right to sell my property. My lawyer said it's a mistake to trust her to put the properties under her name.
