Threatening to hire a lawyer will not get a reaction out of your adjuster. The response will be, go right ahead and have your lawyer call me. He or she may be glad to not have to deal with you any more.
If you get an offer and THEN consult a lawyer, you can ask the lawyer if he will take his fee from the amount over the original offer that he can get you only. But NOT 50-60%, unless you want to rip yourself off! The standard 33-40% is what you should expect to pay. It is not uncommon to agree only to pay the fee on the increased amount (if any) that the lawyer is able to get you.
