ANSWER

If you’re on a joint and several lease in Boulder, one roommate not paying can leave the other roommates and their guarantors responsible for the full rent, unless the lease says otherwise. CU Boulder also says to review the lease, because the exact result depends on the signed agreement.

What CU Boulder says happens

CU Boulder’s Student Legal Services says most Boulder leases are “joint and several,” meaning all tenants and guarantors are responsible for all lease obligations if one roommate doesn’t pay. CU’s Off-Campus Life office also warns there is no standard lease, so the written lease controls the practical result.

  • If the lease is joint and several, the unpaid share can become everyone’s problem.
  • If the lease is individual, the lease language may limit responsibility to each person’s own share.
  • The signed lease is the first thing to check before you assume who owes what.

What to check in the lease right away

CU Boulder says to look for the rent payment process, due dates, late fees, and whether the lease is joint and several or individual. Their roommate agreement template also says a roommate who pays late is responsible for any late fees assessed, but that does not replace the lease itself.

  • Find the exact rent clause and any late-fee clause.
  • Check whether the landlord or lease requires a guarantor or co-signer.
  • Review any written roommate agreement, but treat the lease as the controlling document.
