(TEXT OF BILL BEGINS ON NEXT PAGE)

Be it enacted by the Legislature of the State of Arizona:

Section 1. Section 12-1362, Arizona Revised
Statutes, is amended to read:

START_STATUTE
12-1362.

Dwelling action; offer to repair or replace; jurisdictional
prerequisite; insurance; bifurcated trial; legislative intent

A. Except with respect to claims for alleged
construction defects involving an immediate threat to the life or safety of
persons occupying or visiting the dwelling
or for an alleged
construction defect a seller previously refused to correct or failed to
properly correct
,

a purchaser must first comply
with this article before filing a dwelling action.

B. A seller and the seller's construction
professional who receive a written notice of claim pursuant to section 12-1363
have a right pursuant to section 12-1363 to
make an offer
to
repair or replace any alleged construction defects after sending or
delivering to the purchaser a written
notice of intent

offer
to repair or replace the alleged construction
defects. The seller and the seller's construction professional do
not need to repair or replace all of the alleged construction defects.�
A purchaser may not file a dwelling action until the seller and the
seller's construction professional have completed all intended repairs and
replacements of the alleged construction defects.

C. If a seller or a seller's construction
professional presents a notice received pursuant to section 12-1363 to an
insurer that has issued an insurance policy to the seller or the seller's
construction professional that covers the seller's or the seller's construction
professional's liability arising out of a construction defect or the design,
construction or sale of the property that is the subject of the notice, the
insurer must treat the notice as a notice of a claim subject to the terms and
conditions of the policy of insurance.� An insurer must work cooperatively and
in good faith with the insured seller or the seller's construction professional
within the time frames specified in this article to effectuate the purpose of
this article.� This subsection does not affect the coverage available under the
policy of insurance or create a cause of action against an insurer whose
actions were reasonable under the circumstances, notwithstanding its inability
to comply with the time frames specified in section 12-1363.

D. Subject to Arizona
rules of court, the identified construction professionals shall be joined as
third-party defendants, if feasible.� Subject to Arizona rules of court, for
each construction defect found to exist, the trier of fact in any dwelling
action filed pursuant to this article shall first determine if a construction
defect exists and the amount of damages caused by the
construction

defect and identify each seller or construction professional whose
conduct, whether by action or omission, may have caused, in whole or in part,
any construction defect.� The purchaser has the burden of proof to demonstrate
the existence of a construction defect and the amount of the damages caused by
the construction defect.
The seller has the burden of
proof to establish which construction professional's conduct caused, in whole
or in part, the construction defect.
The trier of fact shall thereafter
determine the relative degree of fault of any defendant or third-party
defendant. The trier of fact shall allocate the pro rata share of
liability based on relative degree of fault. The seller has the
burden to prove the pro rata share of liability of any third-party
defendant. The determination of whether a construction defect
exists, the amount of damages caused by the construction defect and who may
have caused, in whole or in part, the construction defect
shall

may
be bifurcated from and take place in a separate phase
of the trial
or alternative dispute resolution process

from the determination of the relative degree of fault of any defendant or
third-party defendant
, unless the court finds that
bifurcation is not appropriate
.

E. The legislature finds
and determines that given the complexity and multiparty nature of dwelling
actions, it is important to provide a streamlined process for the resolution of
construction defect claims and indemnification claims between the seller and
the construction professionals that is efficient, economical and convenient for
the parties involved.
The legislature further finds
and determines that for the majority of dwelling actions, bifurcation of the
issues of the existence of a defect and causation from the issue of
apportionment of fault is more efficient, fair and convenient for the parties.
�
It is the legislature's intent that the bifurcation process prescribed in
subsection D of this section does not alter the seller's liability under the
seller's implied warranty to the purchaser.
It is the
legislature's intent that the bifurcation process prescribed in subsection D of
this section be used and that the issues of existence of a construction defect,
damages, causation and apportionment of fault be tried in one trial unless the
court finds that the circumstances of the particular case at issue render
bifurcation inappropriate.

prevailing

successful
party
with respect to a
contested issue
reasonable attorney fees

expert witness fees
and taxable costs.�
A purchaser is
deemed the prevailing party with respect to a contested issue if the relief

taxable costs, is more favorable than the repairs or replacements and offers
made by the seller before the purchaser filed a dwelling action pursuant to
section 12-1363.� The seller is deemed the prevailing party with respect
to a contested issue if the relief obtained by the purchaser for that contested
issue, exclusive of any fees and taxable costs, is not more favorable than the
repairs or replacements and offers made by the seller before the purchaser
filed a dwelling action pursuant to section 12-1363.

than any combination of consideration offered or provided by, or repairs or
replacements offered or performed by, the seller pursuant to this article, the
purchaser is deemed to be the successful party from the date that the purchaser
provided a notice pursuant to section 12-1363, subsection A. If the
final judgment is less favorable to the purchaser than any combination of
consideration offered or provided by, or repairs or replacements performed by,
the seller pursuant to this article, the seller is deemed to be the successful
party from the date that the seller provided a response pursuant to section
12-1363, subsection C.

B. An award of attorney fees pursuant
to this section is limited to the amount of fees actually and reasonably
incurred with respect to the contested issue for which the party has been
deemed the prevailing party.� In determining whether the fees actually incurred
with respect to a contested issue are reasonable, the court or tribunal shall
consider all of the following:

1. The repairs, replacements or offers
made by the seller, if any, before the purchaser filed the dwelling action
pursuant to section 12-1363.

2. The purchaser's response to the
seller's repairs, replacements or offers made or proposed, if any, before the
purchaser filed the dwelling action pursuant to section 12-1363.

3. The relation between the fees
incurred over the duration of the dwelling action and the value of the relief
obtained with respect to the contested issue.

4. The amount of fees incurred in
responding to any unsuccessful motions, claims and defenses during the duration
of the dwelling action.

B. The seller may not be reimbursed
for an investigation or repair that the seller performed pursuant to this
article.

C. This section does not alter, prohibit or restrict
present or future contracts that may provide for attorney fees or expert
witness fees.

D. Notwithstanding any other law, in a
contested dwelling action that involves a single purchaser, the court or
tribunal may award the prevailing party with respect to the contested issue
reasonable expert witness fees. The determination of the prevailing
party and the reasonableness of the expert witness fees shall be made using the
same criteria used in determining the award of attorney fees pursuant to
subsections A and B of this section.� This subsection does not apply to a dwelling
action that involves more than one purchaser or an action that is consolidated
with any other dwelling action.� The expert witness fees prescribed in this
subsection are in addition to the taxable costs authorized by section 12-332.

E. For the purposes of this section:

1. "Contested issue" means
an issue that relates to an alleged construction defect and that is contested
by a purchaser following the conclusion of the repair and replacement
procedures prescribed in section 12-1363.

2. "Purchaser" means any
person or entity, including the current owner of the dwelling, who files a
dwelling action during the time period described in section 12-552.

alternative dispute resolution procedures contained in the contract for the
sale of the dwelling or an association's community documents. The
seller's election to enforce any commercially reasonable alternative dispute
resolution procedures contained in the contract for the sale of the dwelling or
an association's community documents does not negate, abridge or otherwise
reduce the seller's right to repair or replace any alleged construction defects
pursuant to section 12-1363.� If the contract for the sale of a dwelling
