 In an existing Financial Services Cloud org using the individual account model, custom objects are used to represent other assets, liabilities, and goals. These objects are related to the Account object via lookuprelationships. For example:

The Other Asset object is used to represent non-financial assets owned by an account holder, such as real estate properties, vehicles, or jewelry.

The Other Liability object is used to represent non-financial liabilities owed byan account holder, such as mortgages, loans, or taxes.

The Financial Goal object is used to represent financial objectives pursued by an account holder, such as retirement planning, education funding, or debt reduction. Verified References: : Salesforce Help Article [10] : Salesforce Help Article [11] : Salesforce Help Article [12]
