Experienced lawyers will ask you for a retainer and quote you an hourly rate for attorney’s services. The retainer should be refundable meaning that any part that is not expended for attorney’s fees or expenses will be refunded to you.
The amount of the retainer will be based on the lawyer’s assessment of how complex the case will be and what will probably need to be done to move it toward a conclusion. The hourly rate for services will depend upon the policies of the law firm and the experience level of the lawyers.
