A computer system and method is disclosed for financial management and estate planning. The system provides data aggregation for both financial and non-financial assets to create a “virtual vault” from which the owner can view all information about his/her portfolio. In some embodiments, the system provides a tree visualization of the portfolio, which allows a structured organization that provides both a high level view and the ability to drill down to an in-depth analysis. In some cases, the system provides segmented permissions in which restricted access could be granted based on module and/or asset in the tree visualization.
