15 U.S. Code § 1647 - Home equity plans
(a) Index requirement
In the case of extensions of credit under an open end consumer credit plan which are subject to a variable rate and are secured by a consumer’s principal dwelling, the index or other rate of interest to which changes in the annual percentage rate are related shall be based on an index or rate of interest which is publicly available and is not under the control of the creditor.
(b) Grounds for acceleration of outstanding balance
A creditor may not unilaterally terminate any account under an open end consumer credit plan under which extensions of credit are secured by a consumer’s principal dwelling and require the immediate repayment of any outstanding balance at such time, except in the case of—
(2) failure by the consumer to meet the repayment terms of the agreement for any outstanding balance; or
(3) any other action or failure to act by the consumer which adversely affects the creditor’s security for the account or any right of the creditor in such security.
This subsection does not apply to reverse mortgage transactions.
(c) Change in terms
(1) In general
No open end consumer credit plan under which extensions of credit are secured by a consumer’s principal dwelling may contain a provision which permits a creditor to change unilaterally any term required to be disclosed under section 1637a (a) of this title or any other term, except a change in insignificant terms such as the address of the creditor for billing purposes.
(2) Certain changes not precluded
Notwithstanding the provisions of subsection  (1), a creditor may make any of the following changes:
(A) Change the index and margin applicable to extensions of credit under such plan if the index used by the creditor is no longer available and the substitute index and margin would result in a substantially similar interest rate.
(B) Prohibit additional extensions of credit or reduce the credit limit applicable to an account under the plan during any period in which the value of the consumer’s principal dwelling which secures any outstanding balance is significantly less than the original appraisal value of the dwelling.
(C) Prohibit additional extensions of credit or reduce the credit limit applicable to the account during any period in which the creditor has reason to believe that the consumer will be unable to comply with the repayment requirements of the account due to a material change in the consumer’s financial circumstances.
(D) Prohibit additional extensions of credit or reduce the credit limit applicable to the account during any period in which the consumer is in default with respect to any material obligation of the consumer under the agreement.
(E) Prohibit additional extensions of credit or reduce the credit limit applicable to the account during any period in which—
(i) the creditor is precluded by government action from imposing the annual percentage rate provided for in the account agreement; or
(3) Material obligations
Upon the request of the consumer and at the time an agreement is entered into by a consumer to open an account under an open end consumer credit plan under which extensions of credit are secured by the consumer’s principal dwelling, the consumer shall be given a list of the categories of contract obligations which are deemed by the creditor to be material obligations of the consumer under the agreement for purposes of paragraph (2)(D).
(4) Consumer benefit
(A) In general
For purposes of paragraph (2)(F), a change shall be deemed to benefit the consumer if the change is unequivocally beneficial to the borrower and the change is beneficial through the entire term of the agreement.
(d) Terms changed after application
If any term or condition described in section 1637a (a) of this title which is disclosed to a consumer in connection with an application to open an account under an open end consumer credit plan described in such section (other than a variable feature of the plan) changes before the account is opened, and if, as a result of such change, the consumer elects not to enter into the plan agreement, the creditor shall refund all fees paid by the consumer in connection with such application.
(e) Additional requirements relating to refunds and imposition of nonrefundable fees
(1) In general
No nonrefundable fee may be imposed by a creditor or any other person in connection with any application by a consumer to establish an account under any open end consumer credit plan which provides for extensions of credit which are secured by a consumer’s principal dwelling before the end of the 3-day period beginning on the date such consumer receives the disclosure required under section 1637a (a) of this title and the pamphlet required under section 1637a (e) of this title with respect to such application.
(2) Constructive receipt
For purposes of determining when a nonrefundable fee may be imposed in accordance with this subsection if the disclosures and pamphlet referred to in paragraph (1) are mailed to the consumer, the date of the receipt of the disclosures by such consumer shall be deemed to be 3 business days after the date of mailing by the creditor.
 So in original. Probably should be “paragraph”.
