Partnerships & Investment Structures
Shared profit, shared risk, written to hold.
Two people, one venture, or one person’s capital and another’s work. Islamic law has structured both for fourteen centuries. English law will enforce both, if the documents are right. Getting them right is the work we lead.
The starting point
If you write nothing, you have still agreed to something
Most partnerships in our community begin without documents: two brothers-in-law, two friends from the mosque, a founder and an uncle with capital. Everyone intends fairness, so nobody wants to seem untrusting by asking for terms.
English law does not wait for you. The moment two people carry on a business in common with a view to profit, the Partnership Act 1890 applies, and its defaults are blunt. If that is not what you meant, the only remedy is to say what you meant, in writing, before you need it.
- Equal shares by default. The Act ignores who invested more, worked harder or took the risk, unless your agreement says otherwise.
- Personal liability. In an unincorporated partnership, your partner’s business debts can become your personal problem.
- Dissolution at will, or by death. Without an agreement, one resignation or one funeral can legally end the firm.
- Memory versus paper. When a dispute comes, the unwritten understanding is whatever the other side now remembers it to be.
The structures
Old structures, modern clothes
The classical forms are not museum pieces. They map cleanly onto the vehicles English commercial life already uses.
- Musharakah Joint venture: capital from all sides
-
All partners contribute capital, all may work, and all share the outcome. Profit is divided in whatever proportions you agree; loss is borne strictly in proportion to capital. That asymmetry is deliberate, and it is the heart of the structure’s fairness.
- Mudarabah Capital on one side, work on the other
-
One party funds, the other manages. Profit is shared by agreed ratio. If the venture loses money without misconduct, the investor loses capital and the manager loses their effort: each risks what they put in, and neither is guaranteed anything.
- The wrapper Company · LLP · partnership agreement
-
These economics can be carried by the vehicles English law knows well: a limited company with a shareholders’ agreement, an LLP with a members’ agreement, or a well-drafted partnership deed. The vehicle is a choice with consequences for liability, tax treatment and formality; the principles travel into whichever one fits.
- The exit Agreed at the start, used at the end
-
How a partner leaves, how their share is valued, what happens on death or incapacity, who may buy whom out: the questions nobody wants to raise at the beginning are precisely the ones the agreement must answer, because by the time they arise it is too late to agree.
Where it goes wrong
The guaranteed return, and other quiet mistakes
The most common request we hear is also the most dangerous: an investor who wants their capital back “whatever happens”, plus a fixed monthly return. However warmly it is phrased, that is not a partnership. It is a loan with interest wearing a partnership’s clothes. Islamic commercial law is unsentimental about this: return follows risk. An investor who bears no risk of loss has lent money, and the fixed return on it is riba.
The honest alternative is not less commercial. It is more precise. Profit ratios can favour the investor. Capital can be protected by how the venture is run, secured, and returned first on winding up. What it cannot be is guaranteed by the person managing it.
- “Fixed return, no risk.” A guaranteed payout to a “partner” converts the arrangement into an interest-bearing loan.
- Vague terms. “We’ll sort the shares out later” is gharar in fiqh and a lawsuit in waiting under English law. Both traditions demand certainty.
- The silent partner with loud expectations. Undefined roles breed resentment; define who works, who decides, and what each is owed for it.
- Loss never discussed. If you cannot say today who bears a loss tomorrow, the structure is not finished.
How we help
The economics agreed, then made enforceable
We start with the substance: what each side is contributing, what each expects, and what should happen in the good years, the bad years and the last year. Our scholars test the arrangement against Islamic commercial principles; our advisers map it onto the right English vehicle. Then the structure goes to drafting. Where regulated legal services are required, these are provided by our partner SRA-regulated law firm.
If your partnership already exists, undocumented or documented badly, the work is the same, done in the right order: establish what has been agreed and contributed so far, then put it on a footing both frameworks respect. Done while relations are good, it is planning. Left until they sour, it is mediation.
LawFiq advises on principles, structure and documentation. We do not promote investment opportunities, introduce investors, recommend financial products or arrange investments. Activities of that kind are regulated by the Financial Conduct Authority and belong with an FCA-authorised firm. If your plans involve raising capital from the public or from strangers, tell us early: the perimeter matters, and we will say what needs an authorised adviser.
Common questions
What partners ask us
We started years ago with nothing in writing. Is it too late?
No, but the longer it runs, the more there is to untangle. An existing partnership can be documented from where it stands: contributions to date established, profits to date acknowledged, and terms agreed from here on. Most partners find the conversation easier than they feared, precisely because relations are still good. That is the time to have it.
Can a non-Muslim partner be part of a structure like this?
Yes. Musharakah and mudarabah describe fair economics: shared risk, shared reward, certainty of terms. Nothing about them requires every party to be Muslim. The agreement is drafted as an ordinary English commercial document; your partner signs terms, not theology.
What happens to the partnership if a partner dies?
Under the Partnership Act’s default rules, death dissolves the partnership, often the worst outcome for everyone, including the family. A well-drafted agreement decides this in advance: how the share is valued, who may acquire it, and how the heirs are paid. It is one of the strongest reasons to document early, and it connects directly to business succession planning.
