Any good lawyer will charge an initial retainer based on the number of hours they expect to resolve a case. So, if the lawyer's hourly rate is $250 and they calculate it will take 40 hours to do all the pleadings, court dates etc, then should charge you $10,000 retainer. So, every minute/hours they work on this case, they (deduct) from the $10,000 they received from you.
Granted, in some cases may cost less, so the lawyer refunds the money to the client, but in others, may have hoops to jump through or other problems, so then asks for more money to keep it going. Now, you have some problems with this lawyer. The 1st one was that you hired him/her after firing a previous lawyer.
That puts this 2nd one on "notice" since many times other lawyers won't touch a client that had a previous lawyer, since they expect problems from the client, or will call the prior lawyer to see why they were fired to decide if they will take you as a client or not. The bills or invoices could be correct to continue your case. But am confused on how much he/she is charging, since says needs another $2,500, then $20,000?
Here is something that most people don't realize, is that most lawyers CANT just stop representing you, if you don't pay. If, the lawyer was to go to court and ask the judge to not represent you anymore, he would have to have a good excuse and money is never a reason, since most judges "frown" on this. The attitude is, you agreed to represent someone, and if they don't pay, then that is their problem, not yours.
Thus, he/she could stall the case, or get it continued, but still be on record as your lawyer. Now, the lawyer can sue you for any money owed to keep this case, but, then the judge would want an accounting of all time spent. This $20,000 sounds like his/her excuse for YOU to fire them, so off the hook.
And, with you having 2 lawyers, for you to find a 3rd lawyer, will be almost impossible, since like stated before, no one wants a client that changes lawyers, since they know they will be having problems with a client. Here are your options. Unknown what state you live in, but file a complaint on this lawyer for the fees and problems you have encountered to the State Disciplinary Division.
Most people think of the bar association, but they do nothing. The Disciplinary Division can disbarr an attorney, or sanction a lawyer if there are some of ethics involved. Usually when a complaint is filed, then they have 30 days to answer, and lawyers hate this, since now they have to spend time answering for the time spent or problems they encountered in your case.
My husband practiced law for over 40 plus years and is retired now. But, he had numerous clients he took on, only to have them not pay after retainer gone, and he got stuck to complete the case. He tried suing many for the money, but another problem with suing, is that his malpractice insurance went up, since insurance knows that when you sue a client, then "maybe" later they may sue you for malpractice, (hey you sue me, so I sue you) even if not winnable, but then insurance gets involved, so they charge higher premiums.
Just some facts to consider. If, you don't live in the USA, then my answer may not apply.
Read your contract. It says you'll keep a certain amount on your retainer. If you're billed for a service that you think a specific charge is inappropriate then discuss that with him/her.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
