Oh my! The red flags are up!

I'm thinking the 'whole' story might be quite interesting here ...

Seriously, legal questions require legal answers. Go to an attorney if you actually think you may be able to do this ... But ...

If I own a warehouse with a partner, 50/50, and I decide to lease out a portion of it without telling or sharing with my partner ...

If I have a shore house with my wife, and I decide to rent out weeks in the summer without telling her ...

Feels like the answer is 'no' ... But I am not a lawyer, nor do I play one on TV...
