For starters, this is the last resort. When a business partnership ends – for personal, financial, retirement or deep-rooted differences – it is critical that the business be protected and the relationship between the owners be respected. If one partner wants the other out, the easiest path is making an offer to buy them out at fair market value. This likely requires a business valuation to support the deal terms. If the relationship is completely strained, the next path is to present clear evidence that the partner you want forced out is in strict violation of your partnership agreement. If no agreements have been broken and if the partners cannot reach a fair settlement, the next best path is appointing a neutral third party to arbitrate the matters, legally. If arbitration is off the table, then you will need to hire business law attorneys to help settle the matter.
