Moved to a new firm after being at the same wirehouse for two decades. Signed the contract a week before, the BOM at the new firm signed it too. BOM said if I signed, I'd receive my first "loan" check on the first day. The day before I start, I'm presented with more loan agreements and a promissary note (thought this was covered in the contract). They look fine and I signed.Upon resigning and arrival at the new firm, after I already started calling clients, BOM tells me that his SVP is holding up the contract over a single previously agreed to clause and is not sure when I'll get my check. BOM says even though he's signed the contract, it's not valid until the SVP signs.I've resigned from my old firm. I've called my clients. In two days over 30% of my book has already signed transfer docs and new account forms. Do I put on the brakes and refuse to sign the client transfer docs? Only experienced insight need reply.
