Inheritance law refers to the set of rules that determine who inherits the assets of a deceased person. It establishes the order of heirs called to receive the inheritance as well as the share that each is entitled to.
In France, inheritance law is primarily governed by the Civil Code. It applies automatically when no specific provisions have been made by the deceased or when part of their estate remains subject to legal rules of succession.
Understanding the mechanisms of inheritance law is essential to anticipate the transfer of one’s assets, protect loved ones, and avoid conflicts among heirs.

What is Inheritance Law?
Inheritance law corresponds to the legal process that organizes the transfer of a person’s assets after their death.
It determines:
- the persons called to inherit;
- the order of priority among heirs;
- the share due to each;
- the rights of the surviving spouse;
- the consequences of the existence or absence of a will.
When the deceased has made no specific provisions, the inheritance is settled according to the legal rules provided by the Civil Code. This is referred to as legal succession.
When the deceased has drafted a will or made certain gifts, this is referred to as voluntary succession, within the limits authorized by law.
What are the principles of inheritance law?
French law is based on several fundamental principles designed to protect the deceased’s family.
Priority given to family ties
The law prioritizes the closest family members to receive the inheritance.
Heirs are divided into different categories called “orders” which determine their rank in the succession.
Protection of forced heirs
Certain heirs benefit from specific protection.
The deceased’s children are generally forced heirs, meaning that a portion of the estate is mandatorily reserved for them.
The deceased cannot therefore freely transfer all of their assets to other persons.
Representation in succession
When an heir dies before the deceased, their own descendants can take their place in the succession.
This mechanism notably allows grandchildren to receive the share that would have gone to their deceased parent.
The Order of Heirs in a Succession
Inheritance law follows a precise order.
Heirs are classified into four main categories.
First order: descendants
The deceased’s children are prioritized.
If they are deceased, their own children (the deceased’s grandchildren) can represent them.
In the presence of children, other family members are generally excluded from the succession.
Second order: parents, siblings
In the absence of descendants, the inheritance goes to:
- the father and mother;
- siblings;
- nieces and nephews by representation.
Third order: ascendants other than parents
When the deceased leaves neither descendants, nor siblings, nor close parents, the inheritance may go to grandparents or great-grandparents.
Fourth order: ordinary collaterals
These include notably:
- uncles;
- aunts;
- male cousins;
- female cousins.
These heirs only intervene in the absence of the preceding categories.
What is the role of the surviving spouse?
The married spouse benefits from specific protection under inheritance law.
In the presence of children
The surviving spouse can generally choose between:
- the usufruct of the entire estate;
- or the full ownership of a portion of the assets.
The rules vary depending on whether the children are common or from a previous union.
In the absence of children
The surviving spouse may receive all or part of the inheritance depending on the potential presence of the deceased’s parents.
The case of the PACS partner
The PACS partner is not a legal heir.
Without a will, they receive nothing from the inheritance.
It is therefore often necessary to plan specific wealth management to protect the surviving partner.
The case of the cohabitant
The cohabitant is also not a legal heir.
Without specific provisions, they have no rights to the inheritance.
Inheritance Law in the Presence of a Will
A will allows one to organize the transfer of their assets according to their wishes.
However, this freedom is not absolute.
Forced heirship
A portion of the estate is reserved for heirs protected by law.
This share varies notably depending on the number of children.
The disposable portion
The disposable portion corresponds to the part of the estate that the deceased can freely dispose of.
It can be allocated to:
- a loved one;
- their spouse;
- an association;
- any other person of their choice.
How does a succession proceed?
Inheritance law takes effect upon death.
Identification of heirs
The notary identifies the heirs and verifies their respective rights.
Estate valuation
All of the deceased’s assets and debts are inventoried:
- real estate;
- bank accounts;
- financial investments;
- life insurance policies;
- potential debts.
Distribution of the inheritance
Once each person’s rights are determined, the estate is distributed in accordance with inheritance rules or the provisions made by the deceased.
Why anticipate your inheritance planning?
Poorly prepared succession can lead to:
- family conflicts;
- heavier taxation;
- significant delays;
- insufficient protection for the spouse or partner.
Organizing the transfer of your assets
Anticipation allows for adapting the transfer to one’s family and financial situation.
Reducing inheritance taxes
Certain strategies allow for optimizing inheritance taxation in compliance with regulations.
Protecting your loved ones
Good preparation notably allows for better protection of:
- the surviving spouse;
- the PACS partner;
- children;
- vulnerable heirs.
Tools for preparing your succession
Several solutions can be used to organize your inheritance planning.
The will
A will allows you to express your wishes and organize the distribution of the disposable portion.
The gift
A gift allows you to transfer part of your assets during your lifetime.
Life insurance
Life insurance is a major transfer tool thanks to its specific legal and tax regime.
Bare ownership and usufruct
This technique allows for separating usufruct and bare ownership to optimize wealth transfer.
