Generally, partners are not compensated for their time.
However, if you have an agreement where the partners are paid for their time and effort, then you should be compensated under that partnership agreement.
Once you have identified the portion of your partnership agreement that entitles you to compensation for payment, present that, together with an accounting showing the value of your services to date, and an offer to be bought out of the partnership.
If you cannot reach a settlement agreement that allows you to dissolve the partnership (remember, the two of you must agree to dissolve the partnership), then you do have a right to file what is called a "dissolution action" with the court that dissolves the partnership by selling off all of the partnership assets, paying any debts, the distributing the remainder between the partners. (This is not a very economical way to dissolve a partnership).
Short of filing a lawsuit, you can try to mediate the dispute with them - contact your local bar association and request referrals to mediators, a third party neutral can often help you reach a mutually agreeable resolution. Use the bar association's referrals to contact a mediator or two, the mediator will then contact the other party to set up a mediation session, and you can go from there - hopefully resulting in a formal or written settlement agreement, and save yourself the time and expense of litigation.
