The Manufactured Housing Forums

Me and my wife live in Toowoomba. I'm giving her money to build a house on land she purchased several years ago. I'm 54 years old, and she's 46. I'm imagining what would happen if she died before I did. Although it's more likely that I'll die first, if she does, I'd like to have the legal right to stay in the house for as long as I required. I realize I won't be able to own the land/property, but I heard that a 30-year lease could be a possibility. I also contact with mandslawyers but they are not dealing in such cases. Is there anyone who knows a decent lawyer who specializes in property law or has experience with property law who might assist me with the legal side of things?

Thanks in advance for any help
