Legal Question in Business Law in California

Re: suppliers level of liability

Well, if you haven't been sued yet, i.e. no service of summons and complaint, your economic best interest is to try to make sure that doesn't happen. It may be cheaper to pay a lawyer to write one or two letters and/or make one or two phone calls on your behalf NOW to explain why you aren't liable than to have to defend a suit in court, even if you have an excellent chance of winning.

This is a stage of a business dispute where showing that you have a strong defense in the best offense.

I'm not 100% sure about the merits of your proposed defense theory -- it would require close examination -- but superficially it sounds convincing and maybe you just need to have a lawyer assist you in calling the consumer's bluff.

If this were a tort case for product liability, it would be a different matter, but on contract principles your case may be sound.

Re: suppliers level of liability

Several questions up front:

1. Have you been paid for your work to date?

2. Have you followed mechanics lien statutes with respect to your cabinets?

3. What do you mean by "installation voids all warranty/guarantee?" The cabinets have to be installed, don't they? If so, why would that negate your warranty?

4. What, specifically, are they claiming to be the defect?

Before I could give you an answer to your question, I would at least need to know these things. Feel free to contact me.
