Complex Estates

Question of the day:

""Alexis, my father owned buildings in France, a consulting company in Germany and accounts in Singapore. Today, my brothers and I no longer speak to one another, the tax authorities are demanding penalties from us and the notaire seems overwhelmed by the joint ownership. How can we escape this deadlock without breaking everything apart?""

A complex estate is not merely a matter of figures or large sums. It is a crossroads where civil law, international taxation, corporate governance structures and, above all, the human dimension all meet. In these moments of vulnerability, conventional wealth management is no longer enough. It must give way to genuine precision engineering.

At Balmont Conseil, we have made complex estates our core business. To meet these challenges, I combine my expertise as a Wealth Engineer with the power of a super-trained wealth-adviser AI. This synergy allows us to model thousands of scenarios, analyze intersecting bodies of legislation and propose liquidation or anticipation solutions that the human mind alone would take months to conceive.

Personalized analysis

What is a complex estate?

An estate is defined as "complex" as soon as it presents legal, tax or relational obstacles that prevent a smooth, amicable settlement. Unlike a "simple" estate (bank accounts and a main residence in France), complexity often arises from four factors:

The nature of the assets under management

An estate made up of a typical real-estate assets (listed historic monuments, forests, income-producing buildings in poor condition), shares in unlisted companies or sophisticated financial investments (Private Equity, trusts) demands an extremely rigorous valuation of the assets in order to avoid any tax reassessment.

The international dimension

As soon as an heir resides abroad or an asset is located beyond the borders, we enter the realm of international jurisdictions. The European Succession Regulation or bilateral tax treaties then become the heart of the case.

The family structure

Blended families, vulnerable heirs or chronic disagreements between siblings often turn the distribution of inheritances into a battlefield. Joint ownership of an estate then becomes a trap in which the estate withers away for want of management.

The professional stakes

Passing on a family business raises questions of governance. Without a Dutreil pact or a prepared wealth-transfer strategy, inheritance tax can force the sale of the operating business, thereby destroying decades of value creation.

The major causes of deadlock and joint ownership

The blocking of an estate is rarely the product of chance. For the wealth of a company director or a self-employed professional, it often results from a rigid wealth architecture or from insufficient estate-planning foresight in the face of an accumulation of friction factors.

Joint ownership of the estate: the enforced "status quo""

Joint ownership is the situation in which several heirs hold rights of the same nature over the same asset, without their respective shares being physically divided. It is often the starting point of family crises:

The unanimity rule: For acts of disposal (selling a building, transferring company shares), the agreement of all the co-owners is mandatory. A single refusal is enough to paralyze the overall strategy.
Day-to-day management made more complex: Even acts of administration require a two-thirds majority of the undivided rights, which can block the upkeep of an asset or the renewal of a commercial lease.
The right of exit: ""No one may be compelled to remain in joint ownership". If an heir demands their share, they can trigger a judicial sale (often at a knock-down price) where the disagreement prevents an amicable division.

The disputed valuation: the trigger of the conflict

The liquidation strategy always begins with an indisputable expert appraisal, because an approximate valuation is a major risk on two fronts:

The risk of tax reassessment: A manifest under-valuation of the assets (often to reduce transfer duties) systematically draws the attention of the authorities, with heavy late-payment penalties and default interest.
The sense of unfairness: If an heir receives an asset over-valued relative to its true market value, they are wronged in the division. Conversely, an under-valued asset unduly favors the person who receives it.
The need for a contradictory appraisal: For complex assets (unlisted companies, atypical real estate), calling upon an independent expert is the only guarantee for defusing suspicions between co-heirs.

The estate-liquidity deadlock

This is the paradox of "asset-rich, cash-poor". An estate may be immense (real estate, operating business) yet lack immediately available liquidity:

The immediate tax pressure: Inheritance tax must be settled within the 6 months following the death. If the rate reaches 45%, and the estate is composed solely of illiquid real estate, the heir is caught by the throat.
The forced sale under duress: In order to pay the tax authorities, the heirs are often forced to sell a flagship asset in unfavorable market conditions, thereby selling off part of the legacy at a loss to settle the tax debt.
The cost of upkeep: Without liquidity to pay the co-ownership charges, the property taxes or the insurance, the estate deteriorates rapidly, leading to a loss of value for all the beneficiaries.

The role of the professionals: an ecosystem of skills

Faced with a complex estate, a single area of expertise is not enough. At Balmont Conseil, we act as the conductor of your advisory firm, coordinating the various parties involved:

Professional	Specific role in the complex estate
The Notary	An indispensable public officer, the notary draws up the deed of notoriety, establishes the inventory and handles the tax declarations.
The Lawyer	Steps in where there is legal action, heavy tax litigation or the drafting of specific testamentary clauses.
The Wealth Adviser (Balmont Conseil)	The strategist. We design the wealth strategies, optimize the tax planning, manage the assets under management and use AI to simulate long-term impacts.
The Genealogist	Called upon for estate genealogy where an heir is missing or the lineage is complex.

Tools and Levers for Anticipation and Resolution

The best way to manage a complex estate is not to let it become complex. However, if the death has already occurred, levers for resolution do exist.

The Gift-partage: the anti-conflict weapon

Anticipating through a donation-partage makes it possible to freeze the value of the assets as at the day of the gift. It is the sovereign tool for avoiding painstaking apothecary's accounts at the time of death and for ensuring an equitable family division.

The Split of Ownership

Using the split of ownership (separating the usufruct from the bare ownership) makes it possible to organize the wealth transfer in a gradual manner, mechanically reducing the transfer costs and the future inheritance tax.

Life Insurance: capital "outside the estate"

Assurance-vie remains a major lever for generating estate liquidity and passing on capital to chosen beneficiaries with reduced taxation, often outside the civil-law rules on the reserved portion (within certain limits), thereby making it easier to compensate an heir in order to release a joint ownership.

The Dutreil Pact

For the entrepreneur, this is the essential mechanism. It allows a 75% exemption on the value of the business for the calculation of duties, provided that retention commitments are respected. Our tax mentoring helps you secure this arrangement, which is often closely pollised by the tax authorities.

How to unblock a settled estate? The key steps

If you are already faced with a deadlock situation, here is the Balmont Conseil methodology:

Comprehensive Audit and Inventory: Identify all the assets, including those abroad, and stabilize the valuation of the assets.
Estate Mediation: Ahead of the courts, we favor estate mediation. Reconciling family relationships through an objective and clearly explained distribution of inheritances.
Analysis of Financing Capacity: Calculating the estate liquidity required to settle the duties without offloading the assets.
Recourse to Specific Mandates: Putting in place a posthumous mandate or a judicial mandate to manage the joint ownership in the event of a total deadlock.
Streamlining the Formalities: Centralizing exchanges with the notary and the authorities to accelerate the liquidation strategies.

Deadlines and obligations: don't get caught out

The management of an estate is governed by strict legal deadlines. A delay can lead to penalties of 0.4% per month, or even a 10% surcharge after 12 months.

The tax timetable: the relentless 6-month deadline

The tax authorities do not wait for family conflicts to subsidize or for the real-estate assets to be sold. The obligations are clear:

6 months: This is the deadline for filing the estate declaration and, above all, paying the duties in full (for a death occurring in mainland France).
12 months: This deadline is extended to one year if the death took place outside France, taking into account the complexity of searching for assets internationally.
The cost of waiting: Any delay incurs default interest of 0.20% per month (the rate in force), on top of which comes a 10% surcharge from the 7th month following the death (if a formal notice has gone unheeded).

The right of option: a strategic decision within 4 months

As soon as the estate is opened, the heirs have a limited time in which to choose their legal position:

The period for reflection: During the 4 months following the death, no one can compel an heir to choose.
Exercising the option: Once this deadline has passed, creditors or co-heirs can summon the heir to make their decision. Without a response within two months of the summons, the heir is deemed to have accepted the estate purely and simply, including any debts.
The importance of the inventory: In a complex estate, these 4 months must be put to good use to carry out a precise inventory in order to decide whether to accept up to the amount of the net assets, thereby protecting one's personal wealth from the deceased's debts.

Why are these deadlines critical in a complex estate?

For an estate made up of company shares (SELARL, holding company), jointly owned real estate or assets abroad, the 6-month deadline is extremely short because it requires:

The valuation of unlisted assets: Obtaining accounting statements and carrying out certified property appraisals takes time.
The release of funds: The banks freeze the accounts as soon as the death occurs. If the estate is predominantly real estate, mobilizing the liquidity to pay the inheritance tax before the 6th month is often a logistical challenge.
The coordination of the parties involved: Between the notary, the chartered accountant, the bankers and the insurers, centralizing the information is the primary cause of delay.

Our role at Balmont Conseil: We act as the conductor to accelerate the gathering of information and to anticipate the tax declarations. We also support you in setting up deferred or installation payment arrangements with the authorities in order to preserve your cash position.
