Prenuptial Agreement in Thailand: What Foreigners Need to Know

A prenuptial agreement can be an important consideration for couples planning to marry in Thailand, particularly where one or both partners already own property, run a business, have savings or investments, or have financial responsibilities from a previous relationship.

A Thai prenuptial agreement sets out how certain assets and property will be treated during the marriage. However, it must be prepared and registered correctly if it is to have legal effect in Thailand.

What Is a Prenuptial Agreement in Thailand?

A prenuptial agreement, sometimes called a prenup or ante-nuptial agreement, is an agreement made before marriage dealing primarily with the couple’s property and financial arrangements.

Without a valid prenuptial agreement, property matters between spouses are generally governed by the standard provisions of Thai law.

A prenup can therefore be useful where a couple wants greater clarity about which assets remain personal property and how property will be managed during the marriage.

When Must a Thai Prenuptial Agreement Be Registered?

Timing is extremely important.

A prenuptial agreement in Thailand must be prepared before the marriage and registered at the same time as the marriage registration.

The agreement should normally be:

• made in writing;
• signed by both future spouses;
• signed by at least two witnesses; and
• entered in the marriage register when the marriage is registered.

If the required formalities are not followed, the agreement may not be legally effective.

Can a Foreigner Have a Prenuptial Agreement in Thailand?

Yes. A Thai national and a foreign national planning to marry in Thailand can enter into a prenuptial agreement.

International couples should take particular care because they may own assets in more than one country.

A Thai prenup may deal with the Thai marriage and property arrangements, but if significant assets are held overseas, separate legal advice may also be needed in the country where those assets are located.

What Can a Prenuptial Agreement Cover?

A properly drafted agreement may deal with matters such as:

• property owned before the marriage;
• savings and investments;
• business interests;
• management of certain assets;
• ownership of personal property; and
• how particular assets are treated during the marriage.

The agreement should be drafted around the couple’s actual circumstances rather than simply copied from a generic template.

Can a Prenuptial Agreement Deal With Everything?

No. A prenup cannot simply override every aspect of Thai family law.

Certain provisions may be ineffective if they conflict with Thai law, public order or good morals.

Issues involving children, custody, maintenance or other family matters may ultimately be determined according to the law and circumstances existing at the relevant time.

Can a Prenuptial Agreement Be Changed After Marriage?

Generally, a registered Thai prenuptial agreement cannot simply be rewritten by the couple after they are married.

Changes after marriage may require authorisation from a Thai court, which is another reason why the agreement should be properly considered and drafted before marriage registration.

Thai Property and Foreign Spouses

Foreigners marrying Thai nationals often have particular concerns about houses, land, condominiums, businesses and investments.

Thailand has restrictions on foreign ownership of land, and a prenuptial agreement does not remove those restrictions.

Couples dealing with substantial property or investments should therefore obtain proper Thai legal advice before marriage.

Should You Use a Thai Lawyer?

For anything beyond very simple circumstances, professional Thai legal advice is sensible.

A qualified Thai lawyer can help ensure that:

• the agreement complies with Thai law;
• the wording reflects what both parties actually intend;
• the agreement is appropriate for the assets involved; and
• the correct registration procedure is followed.

International couples may also need legal advice in another country if they hold substantial assets overseas.
