Conflict of Laws in Property and Succession
From the Persons and Family Relations Law curriculum
TL;DR
When property or inheritance issues cross borders, conflict of laws rules determine which jurisdiction's law applies. The key distinction is between immovable and movable property, with succession typically following the law of the deceased's domicile for movables. These rules prevent legal uncertainty and ensure a consistent approach when multiple laws could potentially govern.
1. The Mental Model
Think of conflict of laws as a legal traffic cop directing which country's or state's laws should be followed when a property or inheritance case involves connections to more than one place. It helps avoid legal chaos by setting clear rules for jurisdiction.
2. The Core Material
Conflict of Laws, also known as Private International Law, provides rules for courts to decide which law to apply when a legal case has "foreign" elements. In property and succession, these rules are crucial because assets (and the people who own them) often move across jurisdictions.
The fundamental distinction here is between immovable property and movable property. This distinction drives which rules are applied.
Immovable Property (Lex Situs)

Immovable property refers to land, buildings, and things permanently attached to the land. The universal rule for immovable property is lex situs, meaning the law of the place where the property is located.
- Rationale: The jurisdiction where the land is situated has the strongest interest in regulating its use, transfer, and ownership. It's impractical for a foreign court to dictate the laws governing land within another sovereign's territory.
- Application: This applies to almost all aspects of immovable property, including:
- Ownership
- Encumbrances (e.g., mortgages, liens)
- Transfer (e.g., sale, gift)
- Validity of wills disposing of immovable property
- Intestate succession (inheritance without a will) for immovables
Movable Property (Lex Domicilii or Lex Rei Sitae)

Movable property includes personal belongings, cash, stocks, bonds, vehicles, and other assets that aren't permanently fixed to land. The rules for movables are more complex and often depend on the specific issue.
- Lex Domicilii (Law of Domicile): This is the predominant rule for succession to movable property. It means the law of the deceased's last domicile (their permanent home) governs how their movable assets are distributed, whether by will or by intestacy.
- Rationale: A person's domicile is considered their personal law, encompassing their legal status, family relations, and their overall estate planning intentions.
- Lex Rei Sitae (Law of the Place Where the Thing is Located): While lex domicilii generally applies to succession, lex rei sitae can apply to the validity of inter vivos (during lifetime) transfers of movable property, or to issues like possession and secured transactions regarding specific movables. However, for succession, lex domicilii usually takes precedence.
Succession
Succession refers to the process of distributing a deceased person's property.
- Immovable Property: Governed by lex situs. If a person dies owning land in Country A, the laws of Country A will dictate who inherits it, regardless of where the deceased lived or died.
- Movable Property: Governed by lex domicilii. If a person dies domiciled in Country B, the laws of Country B will dictate how their movable assets (wherever they are located) are distributed.
Renvoi
Renvoi is a complex issue that arises when the conflict of laws rules of the forum state (where the case is heard) refer to the law of another state, and that second state's conflict of laws rules then refer either back to the forum state (remission) or to a third state (transmission). Many jurisdictions reject renvoi to avoid an endless loop, while others accept it in specific circumstances, especially in succession cases.
Here's a simplified flow for determining applicable law:
graph TD
A["Does the case involve an international/interstate element?"] --> B{What kind of property is involved?};
B -- Immovable Property --> C["Apply Lex Situs (Law of the location of the property)"];
B -- Movable Property (Succession) --> D{"What was the deceased's last domicile?"};
D --> E["Apply Lex Domicilii (Law of the deceased's last domicile)"];
B -- Movable Property (Inter Vivos Transfer) --> F["May apply Lex Rei Sitae (Law of where the movable is located) or Lex Domicilii of the transferor"];
3. Worked Example
Let's consider an example: John, a Canadian citizen, was domiciled in France for the last 20 years of his life. He owned:
1. A house in Spain.
2. A bank account in Switzerland.
3. Stocks in a US company, held in a brokerage account in London.
4. Some personal items (jewelry, car) in France.
John dies without a will (intestate). A dispute arises among his heirs regarding how his assets should be distributed.
Here's how conflict of laws rules would apply:
- Spanish House: This is immovable property. The lex situs rule dictates that the inheritance of the Spanish house will be governed by Spanish law.
- Swiss Bank Account, US Stocks, French Personal Items: These are all movable property. For succession to movables, the lex domicilii rule applies. Since John was domiciled in France at the time of his death, the distribution of these movable assets will be governed by French law, regardless of where these assets are physically located.
So, a French court would apply French law to distribute the movables, and Spanish law would be applied by a Spanish court (or recognized by a French court if it had jurisdiction over the Spanish property dispute) for the immovables.
4. Key Takeaways
- Immovable property (land, buildings) is always governed by the law of its location (lex situs).
- Movable property (cash, stocks, personal items) for succession purposes is generally governed by the law of the deceased's last domicile (lex domicilii).
- This distinction is crucial for determining the validity of wills and intestate succession rules.
- Domicile is not necessarily citizenship or residence; it's the place where a person has established their permanent home.
- Conflict of laws rules aim to provide certainty and avoid contradictory legal outcomes in cross-border cases.
- Renvoi is a complex exception where one country's conflict rules refer to another's, which then refers back or to a third country; it's often rejected.
Common Mistakes to Avoid:
- Confusing citizenship or mere residence with domicile; domicile is a specific legal concept.
- Assuming one country's law will apply to all assets regardless of their nature or location.
- Ignoring the distinction between immovable and movable property; this is the most fundamental error.
- Failing to consider the impact of lex situs for immovables when drafting wills or planning estates.
5. Now Try It
Imagine your aunt, a Philippine citizen, passed away. She was domiciled in California, USA, for the last 30 years. She owns a condominium in Makati, Philippines, a bank account in Manila, and a significant stock portfolio managed by a firm in New York. Outline which law (Philippine law or California law) would govern the succession of each of these assets. What would success look like? You'd have correctly identified the governing law for each specific asset based on its nature and location versus her domicile.
