Property is often one of the most valuable assets considered during a family law property settlement. This may include commercial premises owned by a business, investment properties, development land, or buildings used by a company or trust.
While many people think valuing property is straightforward, the reality can be far more complex. The value does not always relate only to the physical land or building. Instead, it depends on the legal rights attached to the property, such as ownership, lease arrangements, or rights to use the land.
This is where IVS 400 Real Property Interests becomes important. The standard provides guidance on how valuers assess property rights when determining value. Understanding these principles is particularly relevant in family law matters where property interests are tied to businesses, trusts, or investment structures.
Understanding Real Property Interests
Under the International Valuation Standards, a real property interest refers to the legal rights associated with land and buildings. This includes rights of ownership, control, occupation, or use of property.
Importantly, the asset being valued is not always the physical property itself. Instead, it is the legal interest held in that property.
There are generally three types of property interests:
1. Superior ownership interest
This is the highest level of ownership. The holder has full rights to possess and control the property indefinitely, subject to legal restrictions or other interests.
2. Subordinate interests
These typically arise through leases. A tenant may have exclusive possession of a property for a defined period under a lease agreement.
3. Rights of use
In some situations a party may have limited rights to use land or buildings without having exclusive control, such as easements or usage rights.
Understanding exactly which interest is being valued is critical. The value of a leasehold interest can be very different from the value of the freehold property.
Key Valuation Approaches for Property Interests
IVS 400 confirms that valuers generally apply the same core valuation approaches used in other asset valuations.
Market Approach
The market approach compares the subject property with recent transactions involving similar properties. Adjustments are made for differences such as location, building condition, zoning, and market conditions.
Common comparison metrics may include:
Price per square metre of building area
Price per hectare of land
Price per room or unit
However, property assets are rarely identical. Even similar buildings may have different values due to location, planning restrictions, or market conditions.
Income Approach
For investment properties, value is often linked to the income the property generates or could generate. This may include rental income from tenants or the potential rental value of owner occupied property.
When a lease exists, valuers must consider both:
Contract rent, which is the rent agreed under the lease, and
Market rent, which reflects the rent achievable in the open market.
The difference between these two can significantly impact value.
Cost Approach
The cost approach may be used where limited market evidence exists. This approach estimates the cost of replacing the building and then adjusts for depreciation and land value.
Why Property Interests Can Be Complex in Family Law Matters
Real property valuations can become complicated when multiple interests exist in the same property.
For example:
A business may own the building but lease part of it to another entity
A property may be subject to long term commercial leases
A company may operate from premises owned by a related trust
Zoning restrictions may affect development potential
In many cases, the combined value of different interests in a property does not equal the value of the property as a whole.
These issues can materially affect the asset pool in a family law matter.
The Role of Forensic Accounting
In family law disputes, property interests often intersect with business ownership, trusts, or investment structures.
This is where forensic accountants play an important role.
