We are a GC doing a private job in Texas. Our contract terms with the Sub are "we pay when paid". Our contract outlines that once we receive owner payment, we then turn around and pay the subs. A sub of ours just filed a Notice of Intent to file a lien, but we are still waiting on final owner payment before we release the sub's retainage (also specified in the contract). Does our contract protect us or do Texas lien laws trump our contract terms?
