One partner doing most of the work and both partners splitting the profit evenly is not a mistake the law will fix on its own; it is what the law assumes by default. The Uniform Partnership Act (1997) entitles every partner to an equal share of profit regardless of how much time or effort each one actually puts in, unless the written agreement says something different, and it specifically denies a partner any extra pay for extra work beyond reasonable compensation for winding up the business at the end (section 401(h)). So a partner working sixty hours a week next to one working ten has no automatic claim to a bigger share; the claim has to be written into the agreement, going forward, by consent of both partners.

That makes the fix contractual, not something to argue from fairness after the fact. The options below all require the same first step: both partners agreeing to change the deal.

The options, compared

Ways to fix an uneven workload

Option How it works What it needs
A services clause with a guaranteed payment The working partner is paid a fixed amount off the top, before the remaining profit is split in the usual proportion Both partners' consent to amend the agreement (section 401(j)); works best when the imbalance is specific and measurable, like one partner running day-to-day operations
Renegotiate the profit split itself The percentages change going forward, reflecting who actually does the work now rather than who put in the original capital Both partners' consent; cleanest when the imbalance is broad and likely to stay that way
Buy out the underperforming partner The working partner (or the business) purchases the other partner's interest entirely, ending the imbalance by ending the partnership between them Agreement on a price, and usually financing; see how to buy out a business partner
Document first, then decide A log of hours, tasks, and output over a defined period, used to make the case concrete before either partner commits to a fix Nothing from the other partner yet; this step can be done alone and often has to come first

What not to do about it alone

The fix has to be prospective and mutual, which rules out two common reactions. A partner cannot unilaterally withhold or reduce the other's share of profit already earned under the existing agreement, however lopsided the work has been; doing so makes the withholding partner the one in breach, not the one correcting an unfairness. And a change that only one partner wants does not become binding simply because it seems obviously fair: amending the agreement, or agreeing a guaranteed payment that departs from the current split, needs the other partner's actual consent under section 401(j), not just a notice that it is happening.

That consent requirement is also why timing matters. A partner who has quietly resented the imbalance for a year and then demands an immediate, backdated correction is asking for something the law does not support and the other partner has no reason to agree to. The ask that actually works is forward-looking: a specific change starting now, based on a specific, documented pattern, not a retroactive accounting of who worked more over the life of the partnership.

What to do before raising it

A specific, dated record of who did what over the last several months turns "you're not pulling your weight" into a proposal the other partner can actually respond to, rather than a complaint they can simply disagree with: hours worked, decisions made, clients handled, revenue brought in. That record is also what makes the eventual conversation about a fix, rather than about whose memory of the last year is more accurate.

How to tell your business partner it's not working covers how to have that conversation itself; how business partners pay themselves covers how a guaranteed payment or an adjusted split actually gets paid out and taxed once both partners agree to one. If neither a services clause nor a renegotiated split fixes the underlying problem, how to buy out a business partner is the option that ends the imbalance by ending the partnership between the two people, rather than trying to keep adjusting around it.
