I am (happily!) married. But I am also a software engineer, and as such, try to consider every possible path of events ahead of time.
I am about to start a Nevada-based LLC, although the company will be located in NY. Some of the funding for the startup is coming from grants and loans, but some of it would be coming from the joint checking account that belongs to both my wife and I. Let's make it simple. Say the startup costs $10. $6 is coming from loans/grants and $4 is coming from this joint checking account. We have no prenup. I will be running the company 100% with her having absolutely nothing to do with its management or operations.
If, we were to ever get divorced (although please note: I have no plans/intentions on this ever happening!!!), I'm concerned about a situation where my wife would lay claim to owning some portion of the company. Using my simple example above, perhaps this claim would be for 20% (since we have no prenup, we split everything 50/50 and I would own 40% of the company since I/we contributed $4). Don't get hung up on these numbers, I'm just putting them here as a straw man.
My question: how to protect against such a claim, if it ever arose? That is, how to protect my ~40% in the event of a divorce? I ask because I plan on filing the LLC soon.
