Estate-agent commission as a claim: contract, causation and evidence
Claim estate-agent commission only after a clear review of the agency contract, transaction, causation and due date.
30 August 2026, Mag. Bernhard Brandauer, Rechtsanwalt
An estate-agent commission does not arise merely because an agent once made contact. The contract, transaction and required connection must be reviewed before claiming payment.
This article concerns the agent’s commission claim. It is not a general article about assignment, factoring or enforcing an open purchase-price claim.
The file should contain the instruction, property listing, viewings, messages, transaction and commission agreement in chronological order.
Which review comes before the next step?
Answer one short question about the claim. The orientation helps prepare the documents.

What matters most right now?
The next step depends on the contract, documents, deadlines and objections.
Overview of all answers.
Structure documents first
Start with the contract, claim statement, payments and correspondence. A chronology makes the next step reviewable.
Take objections seriously
A dispute, counterclaim and mere delay have different consequences. Claim and evidence should be reviewed separately.
Review the special point quickly
Deadlines, special rules and economic relevance should not be inferred from a general description.
Which documents prove the estate-agent instruction
An agency contract may arise in writing, orally or by conduct. Even so, it must be clear what activity was agreed and when the commission becomes due.
The MaklerG ties the commission claim to statutory and contractual conditions. Consumer transactions add information and form questions.
Why the transaction alone is not enough
The transaction is important, but does not automatically prove that the agent’s work caused it. Listings, contacts, viewings and negotiations may support or weaken the connection.
If a party had already been in contact with the other side, that should be documented. Multiple agents and different commission agreements may also create objections.
Structure causation, due date and objections
An invoice does not replace proof of the conditions for the claim. The agent should present instruction, work, transaction, due date and any withdrawal conditions separately.
Important: The transaction is important, but does not automatically prove that the agent’s work caused it. Listings, contacts, viewings and negotiations may support or weaken the connection.
How the firm reviews the next step
BRANDAUER Attorneys first structure the claim, contract, evidence, objections and deadlines. The firm then reviews whether a lawyer letter, negotiation or court step is sensible.
The strategy depends on the documents and economic relevance. The firm reviews your information and agrees the next step with you personally.
Frequent questions
Does every introduction create an estate-agent commission?
No. The instruction, activity, transaction, causation and other conditions must fit together.
Who must prove causation?
The conditions for the claim must be apparent from the documents, including the instruction, agency work and transaction.
What matters when several agents are involved?
The separate instructions, activities, dates and commission agreements should be documented individually.
