How legal fees are allocated when a claim is partially granted
A partial win does not mean the opposing party will reimburse all attorney fees. For a civil case in Kyiv, we calculate two proportional amounts from the costs already approved by the court and separately show the possible difference between them.

What you should know
- The claimant’s success share is the amount awarded divided by the value of one monetary claim.
- The claimant’s costs are multiplied by the success share, while the defendant’s costs are multiplied by the rejected share of the claim.
- The calculator rounds both proportional amounts independently to the nearest kopeck using the half-up rule.
- The difference between the amounts is only an estimate: the court may award that difference, but is not required to do so.
When this applies
This calculation is for a civil case in which one monetary claim was partially granted. It shows what proportion of the claimant’s costs already determined by the court corresponds to the granted part of the claim, and what proportion of the defendant’s costs already determined by the court corresponds to the rejected part.
The formula is not intended for mixed monetary and non-monetary claims, a counterclaim, multiple claimants or defendants, a settlement, termination of proceedings, or comparing costs from different instances. The basis and allocation rule may differ in those situations.
For a quick check of the four input amounts, use the legal assistance cost allocation calculator. A separate guide to recovering attorney fees and the evidence deadline calculator explain how to claim and substantiate costs and check the procedural deadline.
Applicable deadline or procedure
Let C be the value of the claim, A the amount granted by the court, P the claimant’s costs recognized by the court, and D the defendant’s costs recognized by the court. For this narrow case, the arithmetic is:
- Claimant’s success share:
success = A / C. - Claimant’s proportional amount:
plaintiff gross = P * A / C. - Defendant’s proportional amount:
defendant gross = D * (C - A) / C.
For a calculator estimate, each gross amount is independently rounded half-up to the nearest kopeck: if the third digit after the decimal point is 5 or greater, the second digit increases by one. Only after both amounts have been rounded separately is the smaller amount subtracted from the larger one. This is a technical calculation convention; the Civil Procedure Code does not establish a separate rounding rule of this kind.
Part 10 of Article 141 of the Civil Procedure Code does not make this difference automatic. The court may require the party assigned the larger amount of court costs after allocation to pay the difference to the other party and release the parties from paying the remainder to each other. Therefore, compare the arithmetic result with the operative part of the decision.
What to do step by step
Consider a Kyiv case seeking recovery of 200 000 UAH, in which the court granted 125 000 UAH. The court recognized 30 000 UAH in the claimant’s costs and 16 000 UAH in the defendant’s costs for allocation.
- Success share:
125 000 / 200 000 = 0.625, or62.5%. - Rejected share:
1 - 0.625 = 0.375, or37.5%. - Claimant gross:
30 000 * 0.625 = 18 750.00 UAH. - Defendant gross:
16 000 * 0.375 = 6 000.00 UAH. - Possible difference:
18 750.00 - 6 000.00 = 12 750.00 UAHin the claimant’s favor.
The last amount is an estimate for checking, not an independent claim created by the calculator. If the court applies part 10 of Article 141 of the Civil Procedure Code, it may award 12 750.00 UAH; if it does not, the court’s separately stated allocation of the gross amounts controls.
What to check before filing
First make sure that C is the value of the single monetary claim being compared with A. A reduction of the claim, partial repayment of the debt, or a different amount in the operative part may change the basis, so do not copy the figure from the original claim without checking the decision.
Then verify P and D. These are the amounts the court allowed for allocation after assessing their connection to the case, the evidence, and their justification; they are not necessarily all costs claimed by the parties. On the other party’s motion, the court may reduce legal assistance costs if proportionality requirements were not met; the party making that motion must prove the disproportionality. The court also considers the parties’ conduct when allocating costs and may allocate them differently if there was abuse or the dispute arose from a party’s improper conduct.
Finally, keep both separately rounded intermediate results. Rounding the success share early or calculating the difference from unrounded gross amounts may produce a different kopeck from the sequence used by the calculator.
When to consult a lawyer
For a Kyiv case, legal review is useful if the decision does not specify the costs recognized for each party, the claim value changed, or the operative part does not explain whether the difference under part 10 of Article 141 of the Civil Procedure Code was applied. A lawyer can distinguish an arithmetic error from an issue that needs to be addressed procedurally.
A separate assessment is also needed if the case includes multiple claims, a counterclaim, co-parties, or appeal or cassation costs. Mechanically applying one share in that structure may overstate expected reimbursement or identify the wrong party as payer.
What to prepare
- The value of the one monetary claim considered by the court at the relevant instance.
- The amount of that claim actually granted by the court in its decision.
- The amount of the claimant’s professional legal assistance costs separately determined by the court.
- The amount of the defendant’s professional legal assistance costs separately determined by the court.
Common mistakes
- Entering the fees claimed instead of the amounts the court recognized as eligible for allocation.
- Multiplying both parties’ costs by the granted share without applying the rejected share to the defendant.
- Comparing the calculator result with a different rounding sequence without accounting for its technical convention for the two proportional amounts.
- Treating the difference as an automatic payment without checking what the court ordered under part 10 of Article 141 of the Civil Procedure Code.
- Applying the simple formula to multiple claims, a counterclaim, multiple parties, or costs from different court instances.

Frequently asked questions
Which cost amounts should go into the formula?
Use neither the full fee in the contract nor the amount requested in the application. Use the costs of each party that the court determined were eligible for allocation.
Does the defendant always pay the claimant the difference?
No. Part 10 of Article 141 of the Civil Procedure Code says the court may require the party assigned the larger amount of court costs after allocation to pay the difference to the other party. The operative part of the decision determines the final obligation.
How does the calculator round results to the nearest kopeck?
It calculates the claimant’s and defendant’s proportional amounts separately, rounds each half-up to two decimal places, and only then determines the possible difference. This is a technical calculation convention, not a Civil Procedure Code rule.
Does the formula account for the parties’ conduct in the proceedings?
No. The formula shows an arithmetic proportion, but the court separately considers whether the costs relate to the case, whether they are justified and proportionate, and how the parties conducted themselves procedurally.
Does this calculation work for multiple claims?
No. A combination of monetary and non-monetary claims, a counterclaim, multiple parties, or costs from different instances requires a separate allocation analysis rather than one simplified proportion.
