A joint venture capital provider supplies the equity in a partnership with an operating partner who brings the deal and does the work, and the terms of that partnership get bargained deal by deal. The negotiation is the defining feature. You and the operator sit down over decision rights, the waterfall, what happens if the plan slips, and the document reflects that back and forth. A limited partner in a syndication receives a document that was already drafted for everyone and either signs or passes.
That's the strict meaning. Loosely, plenty of people in the market say "JV equity" for any outside equity in a deal, including a $50k passive check, so the label on a term sheet tells you very little.
The test on your page is whether the consent list is negotiable. Ask for consent over the annual budget, over capital expenditure above a set dollar figure, and over any change to the business plan you underwrote. If the answer is yes and the lawyer marks it up, you're in a JV. If the answer is that the terms are fixed because other investors are coming in on the same paper, you're an LP and should read it as one.
The part that catches people either way is getting out. A partnership interest in a single deal has no market. Transfers usually need the other partner's consent, and there may be a right of first refusal at a formula price. Ask what happens if you want your money back in year three, and ask whether you can be called for more capital, because the answer to both is in the document rather than the term sheet.
