Buying in Monaco Safely: Due Diligence, Deposit and Scams to Avoid

Buying property in Monaco safely: modern seafront residence at Mareterra

Summary of the article in brief :

You plan to buy in the Principality and want to do it safely. The purchase follows a notary-led sequence: written offer, a deposit of about 10% held by the notary, preliminary agreement, due diligence and authentic deed.

This page lists the due diligence checks on title, co-ownership and funds, explains how to pay the deposit without risk and shows the red flags of scams, such as an unlicensed intermediary or a change of bank details.

You also find the acquisition costs of about 9.9% on a resale and the role of the Chambre Immobilière Monégasque.

Is buying property in Monaco safe?

Buying in the Principality follows a framework that places an independent notary at the centre of the transaction. The notary is a public official who acts for neither the buyer nor the seller: he verifies the legal status of the property, drafts the deed and registers the transfer of ownership at the deeds registry.

Sales agencies operate under licence and are registered with the Chambre Immobilière Monégasque (CIM), a professional association that applies financial and professional standards to its members. Safety still depends on the order in which you act: no payment before the notary is involved, a check on every party, and a careful reading of the preliminary agreement.

This page describes common practice. The notary and a legal advisor confirm the rules that apply to your file.

The purchase sequence and the protection at each stage

Each stage has a point where a check protects you. Published guides quote four to twelve weeks, or one to three months, between the acceptance of the offer and the signature of the deed, depending on the complexity of the file.

StageWhat happensProtection point
1. Written offerYou state the price, the validity period and the conditionsThe offer binds both parties once accepted, so every condition is written down
2. DepositAbout 10% of the price is paid after acceptanceThe notary holds the funds, not the agency and not the seller
3. Preliminary agreementA notarised document sets the terms before the deedConditions such as financing are negotiated and written before you sign
4. Due diligenceTitle, charges, co-ownership and funds are checkedThe notary runs official searches and you review the building documents
5. Authentic deedThe deed is signed at the notary's office with the balance and the costsOwnership passes and the transfer is registered at the deeds registry

One published purchase guide states that no legal withdrawal period applies after the agreement. Read the conditions of the preliminary agreement with your notary before you sign, since this document governs your exit.

Due diligence before you sign in Monaco

Due diligence is the set of checks that turns a promising listing into a safe purchase. Start before the offer and complete the list before the preliminary agreement.

The property and its title

  • Title deed: the notary verifies the validity of the title and the chain of ownership
  • Charges and restrictions: the notary checks for easements, charges and restrictions that affect the property
  • Description: surface, number of rooms, cellar and parking spaces match what the listing states
  • Use: the property is a residence or a professional space, and the use matches your plan

The building and the co-ownership

  • Co-ownership regulations: rules on use, works and rental
  • General meeting minutes: decisions on works, disputes and budgets
  • Service charges: the yearly amount and the share paid by the unit; co-ownership fees represent a significant recurring cost in a building with services
  • Planned works: façade, lifts, roof or common areas that lead to extra payments
  • Arrears: confirmation that the seller has paid the charges due

The parties and the funds

  • Seller identity: the person who signs is the owner, or holds a valid power of attorney
  • Origin of funds: anti-money-laundering and know-your-customer checks apply as soon as the offer is made, even without a loan
  • Availability of funds: banks and notaries expect you to show that funds are available and of lawful origin
  • Buyer structure: individual, civil company or foreign company, decided before the offer since it changes the registration duty

Off-plan and new properties

  • Developer: legal status of the development company and track record on past projects
  • Schedule: delivery date and consequences of a delay, written in the contract
  • Payments: instalments linked to construction stages and not to a date
  • Specification: finishes, equipment and surfaces described in an annex
  • Guarantees: ask the notary to confirm in writing which guarantees protect your payments until delivery

How to pay the deposit safely

The deposit is about 10% of the sale price. On a purchase at €2,000,000, it represents €200,000. Guides describe it as paid by bank cheque from a Monaco bank or by bank transfer after the seller accepts the offer, and held by the notary.

  • Pay the notary, never an individual and never the account of an agency employee
  • Confirm the bank details by telephone with the notary's office, using a number taken from an official source and not from an email
  • Treat any change of bank details received by email as suspect until the notary confirms it by voice
  • Keep a written receipt that states the amount, the purpose and the property
  • Read the forfeiture clause: agency guides describe the deposit as acquired by the seller if the buyer withdraws after acceptance, and as refunded to the buyer if the seller withdraws, with a possible penalty equal to the deposit imposed on the seller. The preliminary agreement governs your case.

Scams and red flags in Monaco real estate

Fraud attempts often rely on speed and on money sent outside the notary's framework. Each red flag below has a simple check.

Red flagWhy it mattersWhat to do
A price far below the marketThe IMSEE average for 2025 is €57,569 per m², so a listing at a fraction of this level is a warningCompare with recent sales in the same building and ask for the title
An intermediary without authorisationLicensed agencies are registered with the CIMAsk for the agency's authorisation and check its registration
A payment requested before the notary actsFunds sent outside the notary's account leave you without protectionPay only to the notary, after the offer is accepted
New bank details received by emailA redirected payment is difficult to recoverCall the notary's office on a known number
Pressure to reserve within hoursUrgency prevents checksAsk for a written offer with a validity period
A seller who avoids the notaryThe owner has no reason to avoid the official searchesRequest the title and an introduction to the notary
A rental advertised at a low price with an advance by transferA fake landlord collects the advance and disappearsVisit the apartment and sign through a licensed agency
An off-plan project with little information on the developerYour payments depend on the solidity of the companyAsk for the legal status, the guarantees and past deliveries

What the Chambre Immobilière Monégasque does and does not do

The CIM is a professional association recognised by the authorities. Agencies join after a selection that covers financial and professional standards, and one guide counts more than 100 agencies operating legally in the Principality.

Registration speaks to the standing of the agency. It says nothing about the price of a given property or the condition of a building. Ask each agency for its authorisation and its CIM registration, and ask which mandate it holds on the property you visit, since one agency often represents both sides of a transaction.

Acquisition costs to budget before you commit

A safe purchase starts with a full budget. The table shows the cost on a price of €2,000,000, with a buyer commission of 3% plus 20% VAT, which equals 3.6%.

ItemResale (individual)New propertyOffshore or foreign company
Registration duty4.75% = €95,0001% = €20,00010% = €200,000
Notary feesAbout 1.5% plus €500About 1.5% plus €500About 1.5% plus €500
Buyer commission3.6% = €72,0003.6% = €72,0003.6% = €72,000
TotalAbout 9.9%About 6.1%About 15.1%

Another guide quotes registration and notary charges of 6% to 7.5% on a resale and an agency commission of 3% to 5% plus VAT. Ask for a written statement of every cost before you make an offer.

Who to involve in a Monaco purchase

  • The notary for the legal checks, the deed and the registration
  • A legal advisor to review the preliminary agreement and the buyer structure
  • A tax advisor for the consequences of residency and ownership
  • Your bank for financing and the proof of funds; banks finance between 50% and 70% of the value, over 10 to 25 years, according to one guide
  • A licensed agency, to access properties and organise visits

Yes, when you follow the sequence. An independent notary verifies the title, drafts the deed and registers the transfer, and licensed agencies are registered with the CIM. Your own checks on the building, the funds and the intermediary complete this framework.

The Chambre Immobilière Monégasque is a professional association that registers agencies after a review of their financial and professional standards. It gives you a reference on the standing of an agency, not a guarantee on a given property.

The deposit is generally about 10% of the price, paid after the seller accepts the offer. On a price of €2,000,000, it represents €200,000. The amount varies with the circumstances of the sale and is set in the offer.

The notary holds the deposit, in an account dedicated to the transaction, until the signature of the deed. Do not pay it to an agency employee or to the seller.

It is the usual route, with one precaution: confirm the bank details by telephone with the notary's office, using a number from an official source. Treat a change of details received by email as suspect.

Agency guides describe the deposit as acquired by the seller if the buyer withdraws after acceptance, and as refunded to the buyer if the seller withdraws, with a possible penalty equal to the deposit. Your preliminary agreement governs the outcome.

Guides quote four to twelve weeks, or one to three months, from the acceptance of the offer to the signature of the deed. The time depends on the complexity of the file, the speed of the checks and the financing.

One published guide states that no legal withdrawal period applies after the agreement. Check the conditions precedent with your notary and include the ones you need, such as financing, before you sign.

Check the legal status of the developer, its track record, the delivery schedule, the payment instalments and the guarantees that protect your payments until delivery. Ask the notary to confirm the guarantees in writing.

The usual cases are a price far below the market, an intermediary without authorisation, a payment requested outside the notary's account, changed bank details received by email and a rental advertised at a low price with an advance by transfer.

The notary acts for neither party, so a legal advisor who represents your interests helps you review the preliminary agreement, the buyer structure and the conditions of exit. Balkin works with your advisors throughout the process.

Yes. Many buyers travel once for the signature or give a power of attorney arranged with the notary. Origin-of-funds checks still apply, so prepare your documents before the offer.
