Hey sabina1000,
Generally this isn't a problem at all, but if you're planning to play on the same poker room, you should drop them a line in advance and let them know the circumstances.
In fact, for signing your husband up to PokerStrategy.com you could earn up to $100 via our Tell-a-Friend scheme. Read all the details
here.
Please let me know if you have any further questions or need more help!
Best,
Marc
