Joint ventures, classification and registers: the legal shape you reach the contract with
Nextica Law & Tax sets up and orders the structure a company reaches the tender with: a temporary business grouping under Law 18/1982, with its internal agreement, single management and joint liability towards the contracting authority; registration and upkeep in the Official Register of Bidders and Classified Public Sector Companies and in the Catalan Electronic Register of Bidding Companies; contractor classification under art. 77 of Law 9/2017 and the Regulation approved by RD 1098/2001; and the powers of attorney that let you sign without surprises on opening day.
Two companies that jointly meet the standing requirements and separately do not have a contract. Provided the internal agreement exists before they win it.
What's included
1. Diagnosing your standing against the standard tender documents of the sector you want to enter, to know whether the company qualifies alone or needs structure.
2. Registration and upkeep in the national and Catalan bidder registers, checking that the recorded details match the commercial register.
3. Applying for or renewing contractor classification by groups, subgroups and categories that match the subject matter of the contract.
4. Setting up the joint venture by deed, with its duration tied to the works or service and its single manager holding sufficient powers.
5. Drafting the joint venture's internal agreement
sharing work and result, contributions, who funds cash-flow gaps, decisions requiring unanimity, and default by a member.
6. Reviewing powers of attorney and the validity of office holders, so that on opening day nobody signs without registered authority.
7. Winding up the joint venture when the contract ends, with the split and any outstanding liabilities closed in writing.
THE STRUCTURE YOU BID WITH ALSO FAILS
Choosing a partner and keeping the registers current are not administrative formalities: they are the two decisions that cost the most contracts.
A joint venture has no legal personality of its own
it is a collaboration arrangement, and towards the contracting authority each member answers for the entire contract. Choosing a joint venture partner is a risk decision, not just a commercial one.
Law 18/1982Out-of-date register
registration replaces filing documents and the tender requires it, so a lapsed detail or one that conflicts with the commercial register turns into exclusion on assessment day.
art. 77 Law 9/2017Classification that does not match
it is evidenced by groups, subgroups and categories that must correspond to the subject matter of the contract. Holding classification is not the same as holding it in the subgroup the tender asks for.

Frequently asked questions
Is a UTE a company?
No. The temporary business grouping under Law 18/1982 is a collaboration arrangement with no legal personality of its own: it is executed by deed, its duration is tied to the works, service or supply it exists for, and it acts through a single manager with sufficient powers. Towards the contracting authority the members are jointly and severally liable for the whole contract, not each for their share. That is why the internal split —who does what, who is paid what, and who pays if the other fails— has to be in writing beforehand, and why choosing a joint-venture partner is a risk decision, not just a commercial one.
When is contractor classification required?
For works contracts it is mandatory from an estimated value of €500,000, under art. 77 of Law 9/2017 and the Regulation approved by RD 1098/2001, and it is evidenced by groups, subgroups and categories that must match the subject matter of the contract. For services it is not required, although it can be used to evidence standing if the company holds it. Two practical warnings: classification expires and has to be renewed, and a classification that lapsed on the opening date shuts you out exactly as if you had never held it.
