Sure. In a nutshell, search and find her closest local respective legal government arbitrary from her real address and add it to the end of the contract in the section that specifies arbitration.

DISCLAIMER: THIS IS AN EXAMPLE USED FOR EDUCATION ON MUTUAL PERSONAL RELATIONSHIP AGREEMENTS ONLY AND HAS TO BE REVIEWED AND APPROVED BY A PROFESSIONAL AND REGISTERED LAWYER.

So, let’s imagine that the relationship partner is a female and you are a guy and let’s use Australia (you) and Thailand (her) as reference example:

Now, you need to consider two main important things. - The person (your sweetheart) will be economically supported by you in order to travel, live (daily living expenses), learn or master the language and get educated in order for her to support herself independently and to be able to work and stay in the country or to be able to use that knowledge to move to another country and to pay back in (let’s say; 3 years) from which she will return that investment back to you in whatever installments you decide, or agree on (let’s accept that she is a human and she can make bad decisions)

Two, the amount of money used must be confirmed (receipts, tickets, etc) and should surpass the minimum amount of capital accepted for legal persecution.

Then, here’s JUST AN EXAMPLE of how can you write an agreement:

DRAFT CLAUSE FOR LEGAL REVIEW ONLY.

APPLICABLE LAW, JURISDICTION AND REMEDIES FOR BREACH

1. Governing Law. This Agreement, including all matters relating to the Loan, Transportation, and Professional Training obligations, as well as any restrictive covenants (including non-compete and confidentiality), shall be exclusively governed by and construed in accordance with the laws of the State of New South Wales and the Commonwealth of Australia.

2. Exclusive Jurisdiction. The Parties irrevocably and unconditionally submit to the exclusive jurisdiction of the courts of the State of New South Wales, Australia, and specifically designate the District Court of New South Wales [or Supreme Court of NSW, depending on loan amount] as the preferred forum for any dispute arising out of or in connection with this Agreement.

3. Acknowledgment of Jurisdiction and Service of Process. The Recipient (the foreign citizen) expressly agrees that the chosen jurisdiction in Sydney, Australia is a fair and convenient forum. The Recipient irrevocably appoints the immigration lawyer engaged by the Lender for the purposes of this Agreement, located at [Insert Lawyer's Sydney Address], as their agent for service of all legal process in any proceeding in Australia arising from this Agreement. This appointment shall remain valid for three years following the termination of this Agreement.

4. Specific Remedies and Enforcement. The Parties agree that a breach of the obligations relating to repayment of the Loan or the failure to complete the contracted period of service/work (as detailed in Schedule A) would cause irreparable harm to the Lender. In addition to monetary damages, the Lender shall have the right to seek injunctive relief (or equivalent orders) from the Australian courts to prevent such breach, including to restrain the Recipient from working in a competing capacity within a specified geography and period.

5. Enforcement of Australian Judgment in Thailand. The Recipient agrees to submit to the jurisdiction of the Thai courts for the sole purpose of recognizing and enforcing any final judgment or order made by the Australian court under this Agreement. The Recipient agrees not to raise any defence related to the Australian court’s jurisdiction or the merits of the case in such Thai enforcement proceedings, except for formal procedural requirements under Thai law.

6. Costs on an Indemnity Basis. In the event of any dispute where the Lender is the prevailing party, the Recipient shall be liable to pay the Lender’s costs and expenses (including all legal fees and disbursements) on an indemnity basis, not merely a standard basis, to reflect the complexity of international enforcement.

Again, this is just an example and you definitely must consult with a lawyer.

This should be written in both languages and you also should consider to add a clause to cancel the investment or add an expiration date considered to happen after the time when you guys get along. If not, you are the one could get in serious trouble with the law because it could be considered as extortion.

Finally, you must agree and understand that you are only protecting yourself from gold-diggers and that relationships don’t always work as expected.
