Talk to your lawyer about how you can help maintain good communications. Your lawyer is required to give you a retainer letter detailing how you will be charged, how much it will cost and when you will have to pay. Most lawyers use the time involved in working on a file as one factor in determining the amount to be charged. In a matrimonial breakdown, the costs will vary depending on you and your spouse. The fees that you pay to deal with your marriage breakdown will bear no relation to the fees your neighbours paid to their lawyer in their situation.
Every case is unique.
Discuss costs with your lawyer early in your relationship with him or her. Tell your lawyer accurately and completely what you need and what concerns you have. This early attention to your exact requirements will save you money in the long run. Be sure to discuss fees with your lawyer periodically as your situation proceeds. You have many options besides having matters resolved by the court.
