Multi-Jurisdictional vs Cross-Jurisdictional Estate Planning

Generated on November 3rd, 2025

Multi-jurisdictional estate planning involves one will that governs all assets worldwide, while cross-jurisdictional estate planning typically involves separate wills for each jurisdiction where assets are located. Multi-jurisdictional planning can be more complex as it must comply with all relevant laws, but cross-jurisdictional planning (also known as a “separate situs wills” approach) can streamline the probate process for assets in each location and may be used to reduce estate administration taxes. 

Multi-jurisdictional estate planning

  • One will: A single document is created to handle all assets, regardless of their location.
  • Complexity: The will must be drafted to comply with the laws of every jurisdiction where assets are owned.
  • Potential conflict: A single will can lead to complications if the laws of different jurisdictions conflict with each other or with the will’s provisions.
  • Administration: Can require probate in multiple jurisdictions, potentially leading to higher costs and a longer overall administration timeline. 

Cross-jurisdictional estate planning

  • Multiple wills: You have separate wills, each tailored to the laws of a specific jurisdiction where you own assets.
  • Streamlined administration: Separate wills can simplify the probate process in each jurisdiction, as each will can be probated independently.
  • Tax optimization: This approach can be used to reduce estate administration taxes by only applying them to assets in a specific jurisdiction that requires them.
  • Reduced conflict: By clearly defining which will applies to which assets, you can minimize potential conflicts and ensure a smoother transfer of property.
  • Higher upfront cost: The initial cost of drafting multiple wills is higher, though this may be offset by savings during the estate administration process. 
The best approach depends on your specific situation, including the number and location of your assets, your family structure, and your goals for tax efficiency and ease of administration.

The key difference is the structure: a multijurisdictional approach uses one document, whereas a cross-jurisdictional approach uses multiple, separate documents. Both require specialized legal advice to navigate differences in foreign laws, such as forced heirship rules, and to ensure the client’s wishes are carried out effectively.
