Montana divorce lawyers charge by the hour, by a flat fee for defined work, or by a combination, and they may ask for an advance deposit that is held in a trust account. The one arrangement they may not use is a fee that depends on the outcome. This page, part of our Montana Divorce Guide, explains the structures and the ethics rules behind them. It does not quote amounts, which vary by lawyer and by case.
The Rule Behind Every Fee: Reasonableness
Rule 1.5(a) of the Montana Rules of Professional Conduct says a lawyer "shall not make an agreement for, charge or collect an unreasonable fee or an unreasonable amount for expenses." The rule lists factors that bear on reasonableness, including the time and labor required, the difficulty of the questions involved, the fee customarily charged in the locality for similar services, the amount involved and the results obtained, time limits imposed by the client or the circumstances, and the experience and ability of the lawyer.
Montana's statute on attorney compensation starts from freedom of contract: the compensation of an attorney "is governed by agreement, express or implied" (MCA § 37-61-420(1)). The ethics rule is the limit on that agreement.
Common Fee Structures
| Structure | How it works | What to ask |
|---|---|---|
| Hourly | You pay for the time the lawyer and staff spend, at stated rates. | Who bills at what rate, how time is recorded, and how often you get a statement. |
| Advance deposit | Money paid up front, held in a client trust account, and applied to fees as they are earned and costs as they are incurred. | Whether you must replenish it, and how any unused balance is returned. |
| Flat fee for defined work | One stated fee for a described task, such as preparing the documents for an agreed case. | Exactly what is included, and what happens if the case stops being simple. |
| Limited scope | The lawyer handles only part of the matter, with your informed consent (Rule 1.2(c)). | Which tasks are yours and which are the lawyer's. |
| Contingent fee | Not permitted in a divorce (Rule 1.5(d)(1)). | Nothing. Decline it. |
Hourly billing is suited to work whose size nobody can know in advance, which describes a contested case. A flat fee suits work that can be described in a sentence. Some people hire a lawyer for one defined task and handle the rest themselves. Our article on limited scope representation explains how that works.
Advance Deposits and Trust Accounts
People often call an advance deposit a retainer. The money is still yours until the lawyer earns it. Rule 1.15 sets the handling:
- A lawyer must hold client property "separate from the lawyer's own property," with funds kept in a separate account (Rule 1.15(a)).
- Legal fees and expenses paid in advance must be deposited into a client trust account, "to be withdrawn by the lawyer only as fees are earned or expenses incurred" (Rule 1.15(c)).
- The lawyer must keep complete records of the account and preserve them for five years after the representation ends (Rule 1.15(a)).
- On request, the lawyer must promptly give a full accounting of funds held for you (Rule 1.15(d)).
When the representation ends, the lawyer must refund "any advance payment of fee or expense that has not been earned or incurred" (Rule 1.16(d)). That applies whether the case finished, you changed lawyers, or the lawyer withdrew. See changing divorce lawyers.
What Must Be in Writing
Under Rule 1.5(b), the scope of the representation and "the basis or rate of the fee and expenses for which the client will be responsible" must be communicated to the client in writing, before or within a reasonable time after the representation begins. Changes in the basis or rate must be in writing too. The rule excepts a regularly represented client charged on the same basis and matters whose total cost is foreseeably very small.
Read the agreement for one more item. An attorney who performs services has a lien that attaches to a settlement, decree, or judgment in the client's favor, and the statute directs the attorney to state in the engagement agreement that a lien may be asserted if fees are unpaid, or to notify the client when asserting one (MCA § 37-61-420(2) and (7)). If you do not understand a term, ask before you sign.
Why Contingent Fees Are Barred in a Divorce
In some other kinds of cases a fee may be contingent on the outcome (Rule 1.5(c)). Not in a divorce. Rule 1.5(d)(1) says a lawyer shall not enter into an arrangement for, charge, or collect "any fee in a domestic relations matter, the payment or amount of which is contingent upon the securing of a divorce or upon the amount of maintenance or support or property settlement in lieu thereof."
The rule does not state its reasons. One sensible reading is that a lawyer paid by the size of the award, or only if the marriage ends, would have a personal stake in conflict and against reconciliation or compromise. Whatever the reason, the rule is clear, and no Montana divorce lawyer should offer you such a fee.
Costs That Are Separate From the Lawyer's Fee
A fee agreement distinguishes fees from costs. Costs are amounts paid to others for your case. Depending on the case they can include:
- The court's filing fees. See divorce filing fees and fee waivers.
- A mediator or settlement master. In Missoula County, the local rules say the settlement master should be paid half by each party at the time of the conference unless the parties agree otherwise (Fourth Judicial District Local Rule 9).
- Appraisers, accountants, and other professionals who value property or a business.
- A guardian ad litem, if the court appoints one for a child. The court enters an order for those costs and fees against either or both parents (MCA § 40-4-205(4)).
Our article on what a divorce costs in Montana looks at what drives the total.
When the Other Spouse May Be Ordered to Contribute
If your spouse controls the family's money, the fee question is partly a question for the court. MCA § 40-4-110 lets the court, "from time to time," after considering the financial resources of both parties, order a party to pay a reasonable amount for the other's costs and professional fees. The automatic economic restraining order also allows marital property to be used to pay "a reasonable amount for professional fees and costs" of the case (MCA § 40-4-126(1)). Our article on whether your spouse can be ordered to pay your attorney fees covers the showing required.
