SBA Form 148L: Unconditional Limited Guarantee

Short answer

SBA Form 148L is the Unconditional Limited Guarantee. A guarantor with limited liability signs it, such as an owner under 20% or someone pledging collateral without personal liability. It is signed at closing when the SBA Terms and Conditions require one (SBA Instructions for Forms 148 and 148L).

Edition in use

SBA Form 148L (06/25). SBA last updated its page June 18, 2025. SBA's 06/25 instructions match this edition. SBA still posts the older 10/98 edition at a separate address.

Common mistakes

  • Using the old edition. SBA still posts the 10/98 form on a separate page. The 06/25 edition rewrote the Time option.
  • Checking more than one box. Only one limitation may apply to each guarantor (SBA Instructions for Forms 148 and 148L).
  • Expecting the Time option to end on the written date. It also requires 12 consecutive months current. After a default, it runs until defaults are cured and payments stay current for 12 consecutive months.
  • Expecting a limited guaranty as an owner of 20% or more. Those owners must give an unlimited full guaranty (SOP 50 10 8.1, Sec. A, Ch. 5, Para. A.1.a).
  • Picking the wrong term after a partial sale. A selling owner left under 20% guarantees the full loan amount for at least two years after final disbursement. The lender may use Form 148L (Appendix 15, Para. A.1.c.ii).
  • Assuming the borrower's payments reduce a Maximum Liability cap. Only your own payments count against it, except those that bring the balance below the cap (SBA Instructions for Forms 148 and 148L, Para. D.3).
