Partnership dissolution in the United States is governed almost entirely by state law, and most states have adopted some version of the Revised Uniform Partnership Act (RUPA), drafted by the Uniform Law Commission and now the prevailing model in the large majority of jurisdictions. Around 37 states have adopted some version of the Act, with the rest applying the older Uniform Partnership Act of 1914 or, in Louisiana's case, a distinct civil-law regime. The first practical consequence is that your dissolution agreement must be drafted to the partnership statute of your state of formation, not to a generic national template.
RUPA draws a sharp line that older law did not. Dissociation occurs when a partner ceases to be involved in the business, while dissolution happens when the act requires the partnership to wind up and terminate, and dissociation does not necessarily cause dissolution. RUPA Section 801 lists the events that trigger dissolution and a mandatory winding up, including a partner's express will to withdraw from an at-will partnership and any event the partnership agreement itself designates. The agreement cannot override every default: dissolution caused by the business becoming unlawful, or ordered by a court, cannot be contracted away.
The most important rule for the financial side of any dissolution sits in RUPA Section 807. If the agreement is silent, assets are applied in this order: first to creditors other than partners, then to partners for liabilities other than capital and profits, then to partners for capital contributions, and finally to partners for their share of profits. Creditors always come before partners, and a dissolution agreement that tries to pay partners first is unenforceable against the firm's lenders. RUPA also lets a partnership file a Statement of Dissolution, which provides constructive notice to third parties and limits a partner's lingering authority to bind the firm.
